ABOUT INDEPENDENT BANK GROUP Independent Bank Group, Inc. (”IBTX” or “Company”), through its wholly owned subsidiary, Independent Bank, provides a wide range of relationship - driven, commercial - banking products and services tailored to meet the needs of businesses, professionals and individuals. Independent Bank Group operates in four market regions located in the Dallas/Fort Worth, Austin and Houston, Texas and the Colorado Front Range areas. 2017 HIGHLIGHTS • Record earnings with increases across major, income - related metrics • Organic loan growth of 12.2% • Completed largest acquisition to date • Announced acquisition of Integrity Bancshares, Inc. • Raised additional capital to support continued growth ANNUAL MEETING OF SHAREHOLDERS May 24, 2018 | 3:30 p.m. The Grand Hotel, The Grand Ballroom 114 West Louisiana Street McKinney, Texas 75069 ANNUAL REPORT 2017LETTER TO SHAREHOLDERS Independent Bank Group continued to follow proven business practices throughout 2017, growing organically and through completion of our largest acquisition to date – the merger with Carlile Bancshares, Inc. This landmark acquisition complemented our existing footprint by adding more locations throughout Dallas/Fort Worth, and introducing our organization to new markets in Colorado; as well as substantially increasing the size of our balance sheet and market capitalization. Financials continued to outperform. At year - end 2017, the Company earned a record $76.5 million, and the supporting metrics were all equally strong. I believe our solid track record can be attributed to the stewardship of an experienced board combined with proven credit and lending practices, quality people on the front lines and talented operational teams, driven by a genuine desire to help our customers. The company has remained on a post - IPO trajectory that has seen the organization effectively double in assets every two years. As we move for- ward, growth rates will naturally adjust to accom- modate our larger base. However, our expansion has spurred fresh and far - reaching organizational LETTER TO SHAREHOLDERS initiatives. The focus on process improvement and efficiency measures is now paramount to keep costs in line, and to support sustained growth. It was also a year to refine our purpose as we became more intentional of how we communicate and implement strategies to achieve our goals. We continued to fuel local economies and make an impact on those around us. Our ethos remains intact, and our concern for the commonwealth is steadfast. To that, I’m happy to report, some of our longer - range philanthropic projects, such as the Federally Qualified Health Center in McKinney, have taken root and come to life. As I reflect on the year, I am both energized and inspired by the breadth of our accomplishments and unwavering dedication of our banking family. supporting more communities. The last decade has seen more rapid expansion, and like everything else, technology has changed “how” we do things. However, the essence of our business, and what led me into banking still commands my interest. Because of the nature of our business, and our interaction with so many industries and organiza- tions, we are often granted an inside view of the economy. This offers endless opportunities to learn from others, helping shape positive outcomes and leading with a courageous heart. After three decades guiding this organization, my commitment to growing our company, enhancing shareholder value and building healthy communities is greater than ever. 30 YEARS Warmest Regards, We purchased a small bank in Farmersville, Texas back in 1988 with local support, some experi- ence and plenty of grit.

The organization maintained excellent asset quality metrics, and continued to focus on improving overall efficiency. The Company followed its proven growth strategy in 2017, announcing the acquisition of Integrity Bancshares and raising additional capital to support future expansion. We remain committed to enhancing shareholder value and approach all major decisions with that objective in mind. 2016 2017 $53.5 million $76.5 million INCOME The Company reported a year-over-year increase in Earnings per Share of 3.125%.

Welcome to high - performance, purpose - driven banking; where success is built around our people. In Pursuit of Performance Our mission and corporate culture will always uphold and embrace service to community. However, we oper- ate in a competitive landscape, where financial metrics matter. To that end, getting the most from our capital, our people and processes is a significant contributor to financial success. We continue to look more closely at how we do things and approach every process with the expectation that change delivers an increase in performance. Fortunately, our growth is an ally. With the benefit of scale, we can provide the additional infrastructure to identify need more precisely and develop effective solutions. The newly formed Program Management team has been tasked with supporting strategic decisions through analysis, with a concentration on increased performance and improved customer experience. Every decision strategy, before we allocate resources or affect change, must move the needle forward; be it an improvement in efficiencies, cost - savings, revenue enhancement or productivity. In the past year, we’ve made significant strides to centralize processes, yet still keep local banking teams empowered and engaged. Technology, time manage- ment, departmental structures, data and payment process- ing, document management, accounting and communi- cations are all candidates for performance improvements. Technology Powers Banking Excellence Customers are plugged-in. We use complex software to support and protect our customers as they conduct business and manage their banking operations using digital tools. Our Information Technology (IT) workgroup is constantly tasked with supporting these business objectives while balancing and adapting to an ever - changing landscape. In 2017, the Information Technology Department began to transition from an operationally focused group to being more strategic in nature, acting as an internal professional services technology team for all lines of business. This group focuses on improving business unit efficien- cies and accomplishing business objectives through the enhanced use of technology. In addition, these objectives are being connected to positive customer experiences. 8 $23.76 Tangible Book Value per Common Share 15.46% Adjusted Return on Tangible Equity1 18% Increase in Dividend2 1Calculated using adjusted net income 22016 -2017 All domains are developing relationships with specific business units, providing thought leadership and building technology solutions that best serve our communities and clientele. The Information Security group, which manages the protection of our data and technology infrastructure, is also expanding its reach. They continue to strengthen our security posture and are performing more robust reviews of our data, systems and processes. Plus, they are imple- menting innovative outreach programs that educate our workforce and assure we exceed best practices. The financial services industry is facing more sophisti- cated cyber security threats every year. Our Information Security group is aggressively addressing the landscape to stay ahead of potential threats. ANNUAL REPORT 2017Our regional lending leaders are forging lasting relationships in every community we serve. Pictured (front: left to right) Charlie Rigney, Tony Clark. (Back: left to right) Jonathan Sparling, Johnny Bratcher, Dan Strodel, Clay Hoster, Mark White, Glenn Monroe. A Strong Credit Culture Lending is the foundation of any bank. By developing strong relationships and a deep understanding of every customer’s unique needs, Independent Bank has become an industry leader in commercial finance and community banking. We continue to foster a strong credit and lending culture, managed by a group of outstanding regional leaders. Our teams know their markets and focus on proven methods with sound decision - making. More than that, they connect communities. Independent Bank is built around people of character, who understand the value gained by investing in sustainable projects that make a lasting impact. TOTAL NON- PERFORMING ASSETS 7 1 0 2 SUPERIOR CREDIT QUALITY 0.26% 0.01% CHARGE OFFS ARE HISTORICALLY LOW Engaging with Small Business Builds Community We are very proud of our community - lending practices. We’re helping create economic momentum that carries into communities; fostering growth and energizing local businesses. We accomplish these goals by funding projects such as medical facilities, warehouse space, and hospitality and education venues. In 2017, Independent Bank earned Preferred Lender status from the U.S. Small Business Administration (SBA). Under the Preferred Lenders Program (PLP), SBA lenders, such as Independent Bank, are granted wide authority over loan approvals and processing. This allows the Bank to make faster decisions, positioning our SBA lending program as an attractive option for business owners. It’s a perfect accompaniment to Independent Bank’s local - lending initiatives. Independent Bank can now deliver small business customers the full range of SBA loan products through a more streamlined loan - approval process. ANNUAL REPORT 2017New Headquarters on the Horizon During 2017, we announced plans to build a new corporate headquarters located at the McKinney Corporate Center Craig Ranch. The approximately 165,000 square - foot headquarters will make a statement in McKinney and allow space for Independent Bank’s anticipated growth. Building our new corporate headquarters closer to the Metroplex and Dallas/Fort Worth Airport supports our recruiting and retention efforts. Approximately 400 employees are expected to occupy the new headquar- ters upon completion of Phase I. The campus also allows for a second phase of expansion. The headquarters will be situated on a 10.4 - acre parcel of land at State Highway 121 and Grand Ranch Parkway. The new location will provide employees with views of greenspace and a water feature, and direct access to walking trails. KDC was selected to develop the new site, and broke ground in January 2018. An anticipated occupancy is set for early 2019. KDC will pursue LEED Silver certifica- tion. SmithGroup J JR is the architect and Rogers - O’Brien Construction Company, LTD is the general contractor. We are grateful for the support of the City of McKinney and the McKinney Economic Development Corporation. “ We’ve managed to bring together two large and complex organizations while keeping the “ relationships we have with our customers strong — and that’s a remarkable thing. - James C. White Executive Vice President/Chief Operations Officer A Bank Built Around Our People We believe that building strong healthy communities begins within. As a result, the Bank continues to support self - improve- ment initiatives, educational assistance, talent development and internal advancement for the current workforce. Through either promotion or transfer, approximately twenty - five percent of IB’s new positions were filled by internal candidates last year. The Human Resources (HR) team also launched a new wellness program designed to help our people lead more productive, happier lives. In 2017, HR was tasked with onboarding the Carlile/Northstar employees while continuing to support the existing staff and an expanding corporate infrastructure. Forty percent of the Bank’s employees now carry a tenure of five years or longer, and we are leaning more on our Human Resources and Communications teams to extend our brand and develop programs aimed to attract, recruit, develop, retain and sustain this high - performing, diverse workforce. Serving and operating in desirable, growth - oriented markets has been a significant contributor to our successes. Major employers continue to migrate into Texas and Colorado, adding to the already attractive landscape. We are confident that by remaining engaged, flexible and responsive, Independent Bank will continue to appeal to those ready to make a positive impact and preserve our position as a premier employer. 10 ANNUAL REPORT 2017 On April 3, 2017, Independent Bank Group successfully completed its milestone acquisition of Carlile Bancshares. At close, Carlile Bancshares, through its wholly owned subsidiary, Northstar Bank, operated 24 full - service banking locations in Texas and 18 full - service banking locations in Colorado; with total assets of over $2.3 billion. Carlile Bancshares Empowering Our Workforce The merger of Carlile/NorthStar Bank increased the organization’s scale dramatically, and extended our brand into a number of very attractive markets. Our presence in the Dallas/Fort Worth Metroplex, specifically Fort Worth and the Denton County area, was significantly strengthened. Carlile/Northstar also provided a solid entry point to the Colorado Front Range area, including Denver and Colorado Springs. The acquisition afforded opportunity to streamline work- flow and expand our service offerings. Carlile/Northstar brought with it a turnkey warehouse lending operation, Small Business Association Preferred Lender status and robust, internal business solutions. After closing, we sharpened our footprint by selling nine branches in Colorado, as well as the Marble Falls, Texas location. Independent Bank ended the year with 70 branches holding $8.7 billion in assets; which equates to a simple average of approximately $125 million per branch. As our footprint and employee - base grows, keeping teams connected and well - informed becomes more critical to our success. It requires intention reinforced by dynamic, versatile tools. The Bank renewed its focus on Corporate Communications by launching robust solutions and automating systems. The Marketing & Communications team was able to eliminate layers of communication; strengthen and streamline processes; provide organizational clarity and support departments across the organization. Our unique brand of banking extends from the Gulf Coast of Texas to the Rocky Mountains. We recognize the value of a strong mission statement. By turning up the volume of our messaging and promoting a culture already in place, we’ve seen improvements in many areas including employee recognition, onboarding and engagement. We also continue to define and distill what makes Independent Bank special. This includes putting programs front and center that develop collaboration and team- work, such as our employee referral bonus and milestone recognition programs. ANNUAL REPORT 2017 HOUSTON Up to the Challenge Like many, we were shocked by the devastation caused in the Houston region by Hurricane Har- vey in 2017. In response, IB employees from across the Bank’s footprint came together to show support for their colleagues, as well as those directly impacted and in need. What emerged through the hardship, was the remarkable resil- ience and generosity of our people. $79,394 Hurricane Harvey Relief Funds Today, while most of the Houston communi- ty has returned to business as usual, some ar- eas continue to face storm - related challenges, while federal relief funding begins to reach those inneed. The Bank continues to assist with recovery - related efforts that extend beyond traditional fundraising, such as prioritizing lend- ing opportunities that support local infrastructure projects. We continue to believe in the vibrancy of Hous- ton. So much so, that on November 28, 2017, we announced our intent to purchase another Houston - area bank: Integrity Bancshares. This will be our third acquisition in Houston. Integrity Bank has a demonstrated history of growth and strong earnings, with locations in attractive sub - markets of Houston. Houston has been a key contributor to our growth. Increasing our branch and employee network there is a big positive. We look forward to wel- coming Integrity Bank’s clients, shareholders and employees to Independent Bank Group in 2018. Making a Difference We believe that success commands we take a larger role assisting those who cannot help themselves. Bank leadership is fortunate to have many opportunities to do meaningful work outside of our core. Years ago we identified a serious challenge facing people in our local community; the lack of access to quality healthcare. As a result, we made it a priority to address this deficiency. Now, our long - standing efforts to establish a Federally Qualified Health Center to serve McKinney, Texas have begun to bear fruit. Annual Community Grants remain a keystone of our giving program. In 2017, Independent Bank proudly provided $278,500 to support the work of non - profits in North Texas, Houston, Austin and Waco. The full list is available online at ibtx.com/community. This totals more than $780,000 in grants since the program launched in 2015. RECOGNITION AND AWARDS We’re proud of the reputation we’ve built and the milestones we’ve reached. Award highlights from 2017 include being named #20 in Forbes Magazine’s Best Banks in America.

The Company acquired 42 new locations as part of the transaction. The assets acquired in this acquisition represented 82.2% of the Company’s asset growth in 2017. Pending Acquisition of Integrity Bancshares, Inc. On November 28, 2017, the Company entered into an Agreement and Plan of Reorganization (the Reorganization Agreement) to acquire Integrity Bancshares, Inc. (Integrity), and its subsidiary, Integrity Bank, SSB, Houston, Texas, a Texas state savings bank.

The transaction is subject to certain conditions, including the approval by shareholders of Integrity and customary regulatory approvals. Future Opportunities. The Company plans to explore additional opportunities in the growing sub markets within the Company’s current market regions and attractive new markets in Texas such as San Antonio. Factors considered by the Company to evaluate expansion opportunities include (a) similar management and operating philosophy, (b) accretive to earnings and increase shareholder value, (c) ability to improve efficiency, (d) strategic expansion of Company footprint and (e) enhance market presence in existing markets. The Company has a scalable infrastructure and experienced acquisition team which it believes will enable the Company to successfully integrate acquired banks. The Company intends to remain disciplined in its approach to acquisitions using appropriate valuation metrics. 2 Improve Efficiency and Increase Profitability. The Company employs a systematic and calculated approach to increasing the Company’s profitability and improving the Company’s efficiencies. The Company continues to update its operating capabilities and create synergies within the Company in the areas of technology, data processing, finance, compliance and human resources. The Company believes that the Company’s scalable infrastructure provides the Company with an efficient operating platform from which to grow in the near term without incurring significant incremental noninterest expenses, which will enhance the Company’s returns. Independent’s Community Banking Services The Independent Way. Nearly a century after the Company’s beginning, the Company’s dedication to serving the needs of businesses and individuals in the Company’s communities remains stronger than ever. The Company strives to provide the Company’s customers with innovative financial products and services, local decision making and a level of service and responsiveness that is second to none. The Company’s innovative and independent spirit is balanced by adherence to fundamental banking principles that have enabled the Company to remain strong, sound and financially secure even during challenging economic times. The Company is also steeped in a tradition of civic pride as evidenced by the investment of the Company’s time, energies and financial resources in many local organizations to improve and benefit the Company’s communities. Lending Operations. Through Independent Bank, the Company offers a broad range of commercial and retail lending products to businesses, professionals and individuals. Commercial lending products include owner-occupied commercial real estate loans, interim construction loans, commercial loans (such as SBA guaranteed loans, business term loans, equipment financing and lines of credit and energy related loans) to a diversified mix of small and midsized businesses, and loans to professionals, including medical practices. Retail lending products include residential first and second mortgage loans and consumer installment loans, such as loans to purchase cars, boats and other recreational vehicles. The Company’s strategy is to maintain a broadly diversified loan portfolio by type and location. The Company’s loans are primarily real estate secured loans spread among a variety of types of borrowers, including owner occupied offices for small businesses, medical practices and offices, retail operations and multi-family properties. The Company’s loans are diversified geographically throughout the Company’s Dallas/North Texas region (approximately 52%), the Company’s Houston region (approximately 22%), the Company’s Austin/Central Texas region (approximately 20%) and the Company's Colorado Front Range region (approximately 6%). See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Loan Portfolio” for a more detailed description of the Company’s lending operations. Deposits. Deposits are the Company’s principal source of funds for use in lending and other general banking purposes. The Company provides a full range of deposit products and services, including a variety of checking and savings accounts, debit cards, online banking, mobile banking, eStatements and bank-by-mail and direct deposit services. The Company also offers business accounts and management services, including analyzed business checking, business savings, and treasury management services. The Company solicits deposits through its relationship-driven team of dedicated and accessible bankers and through community focused marketing. Other Services. In connection with our relationship driven approach to our customers, the Company offers residential mortgages through our mortgage brokerage division. As a mortgage broker, the Company originates residential mortgages which are sold into the secondary market shortly after closing. The Company also provides wealth management services to its customers including investment advisory and other related services. Competition The Company competes in the commercial banking industry solely through Independent Bank and firmly believes that Independent Bank’s long-standing presence in the community and personal service philosophy enhance the Company’s ability to attract and retain customers. This industry is highly competitive, and Independent Bank faces strong direct competition for deposits, loans and other financial-related services. The Company competes with other commercial banks, thrifts and credit unions. Although some of these competitors are situated locally, others have statewide or nationwide presence. In addition, the Company competes with large banks in major financial centers and other financial intermediaries, such as consumer finance companies, brokerage firms, mortgage banking companies, insurance companies, securities firms, mutual funds and certain government agencies as well as major retailers, all actively engaged in providing various types of loans and other financial services. The Company believes that its banking professionals, the range and quality of products that the Company offers and its emphasis on building long-lasting relationships distinguishes Independent Bank from its competitors. 3 According to S&P Global Market Intelligence, as of June 30, 2017, the Company had the 13th largest deposit market share in Texas and the 34th largest deposit market share in Colorado. We believe that our strong market share is a reflection of the Company’s ability to compete with more prominent banking franchises in our markets. Employees As of December 31, 2017, the Company employed approximately 924 persons. The Company provides extensive training to the Company’s employees in an effort to ensure that the Company’s customers receive superior customer service. None of the Company’s employees are represented by any collective bargaining unit or are parties to a collective bargaining agreement. The Company believes that the Company’s relations with the Company’s employees are good.

The U.S. banking industry is highly regulated under federal and state law. Consequently, the growth and earnings performance of the Company and its subsidiaries will be affected not only by management decisions and general and local economic conditions, but also by the statutes administered by, and the regulations and policies of, various governmental regulatory authorities. These authorities include the Board of Governors of the Federal Reserve System, or Federal Reserve, the Federal Deposit Insurance Corporation, or the FDIC, the Office of the Comptroller of the Currency, or the OCC, the Texas Department of Banking, or TDB, the Consumer Financial Protection Bureau, or the CFPB, the SEC, the Internal Revenue Service and state taxing authorities. The effect of these statutes, regulations and policies, and any changes to such statutes, regulations and policies, can be significant and cannot be predicted. The primary goals of the bank regulatory scheme are to maintain a safe and sound banking system and to facilitate the conduct of sound monetary policy. The system of supervision and regulation applicable to the Company and its subsidiaries establishes a comprehensive framework for their respective operations and is intended primarily for the protection of the FDIC’s deposit insurance fund, the banks’ depositors and the public, rather than the Company’s shareholders or creditors. The description below summarizes certain elements of the applicable bank regulatory framework. This description is not intended to describe all laws and regulations applicable to the Company and its subsidiaries, and the description is qualified in its entirety by reference to the full text of the statutes, regulations, policies, interpretive letters and other written guidance that are described herein. 4 The Dodd-Frank Act. The Dodd-Frank Wall Street Reform and Consumer Protection Act, known as the Dodd-Frank Act, was signed into law on July 21, 2010. The Dodd-Frank Act has had a broad impact on the regulation and operation of financial institutions. The Dodd-Frank Act codified the “source of strength” doctrine, authorized the CFPB and implemented new mortgage lending rules, established a risk retention rule, imposed limitations on trading activities, made permanent the deposit insurance limit of $250,000 and increased the minimum Deposit Insurance Fund reserve ratio, enhanced the restrictions on transactions with affiliates, and expanded corporate governance requirements and executive compensation limitations for U.S. public companies. Many of the requirements have recently been implemented, or are in the process of being implemented. Given the uncertainty associated with the manner in which the Dodd-Frank Act will be implemented and interpreted, the full impact of these changes will not be known for several years. The changes resulting from the Dodd-Frank Act, to the extent known, are incorporated in the discussion of supervision and regulation of the Company and Independent Bank below. The Company’s management continues to review the provisions, implementation, and legislative status of the Dodd-Frank Act and assess its potential impact on the Company’s operations. Independent Bank Group as a Bank Holding Company As a bank holding company, the Company is subject to regulation under the Bank Holding Company Act of 1956, or the BHC Act, and to supervision, examination and enforcement by the Federal Reserve. The BHC Act and other federal laws subject bank holding companies to particular restrictions on the types of activities in which they may engage, and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations. The Federal Reserve’s jurisdiction also extends to any company that the Company directly or indirectly controls, such as the Company’s nonbank subsidiaries. Regulatory Restrictions on Dividends; Source of Strength. The Company is regarded as a legal entity separate and distinct from Independent Bank. The principal source of the Company’s revenues is dividends received from Independent Bank. As described in more detail below, Texas state law places limitations on the amount that state banks may pay in dividends, which Independent Bank must adhere to when paying dividends to the Company. The Federal Reserve has issued a policy statement that provides that a bank holding company should not pay dividends unless (a) its net income over the last four quarters (net of dividends paid) has been sufficient to fully fund the dividends, (b) the prospective rate of earnings retention appears to be consistent with the capital needs, asset quality and overall financial condition of the bank holding company and its subsidiaries and (c) the bank holding company will continue to meet minimum required capital adequacy ratios. Accordingly, the Company should not pay cash dividends that exceed its net income in any year or that can only be funded in ways that weaken its ability to serve as a source of financial strength for its banking subsidiaries, including by borrowing money to pay dividends. Under Federal Reserve policy, bank holding companies have historically been required to act as a source of financial and managerial strength to each of its banking subsidiaries, and the Dodd-Frank Act codified this policy as a statutory requirement. Under this requirement, the Company is expected to commit resources to support Independent Bank, including at times when the Company may not be in a financial position to provide such resources. Any capital loans by a bank holding company to any of its subsidiary banks are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary banks. As discussed below, a bank holding company, in certain circumstances, could be required to guarantee the capital restoration plan of an undercapitalized banking subsidiary. If the capital of Independent Bank were to become impaired, the Federal Reserve could assess the Company for the deficiency. If the Company failed to pay the assessment within three months, the Federal Reserve could order the sale of the Company’s stock in Independent Bank to cover the deficiency. Scope of Permissible Activities. Under the BHC Act, the Company is prohibited from acquiring a direct or indirect interest in or control of more than 5% of the voting shares of any company that is not a bank or financial holding company and from engaging directly or indirectly in activities other than those of banking, managing or controlling banks or furnishing services to or performing services for its subsidiary banks, except that the Company may engage in, directly or indirectly, and may own shares of companies engaged in, certain activities found by the Federal Reserve to be so closely related to banking or managing and controlling banks as to be a proper. These activities include, among others, operating a mortgage, finance, credit card or factoring company; performing certain data processing operations; providing investment and financial advice; acting as an insurance agent for certain types of credit-related insurance; leasing personal property on a full-payout, nonoperating basis; and providing certain stock brokerage and investment advisory services. In approving acquisitions or the addition of activities, the Federal Reserve considers, among other things, whether the acquisition or the additional activities can reasonably be expected to produce benefits to the public, such as greater convenience, increased competition, or gains in efficiency, that outweigh such possible adverse effects as undue concentration of resources, decreased or unfair competition, conflicts of interest or unsound banking practices. Notwithstanding the foregoing, the Gramm-Leach-Bliley Act, also known as the Financial Services Modernization Act of 1999, effective March 11, 2000, or the GLB Act, amended the BHC Act and eliminated the barriers to affiliations among banks, 5 securities firms, insurance companies and other financial service providers. The GLB Act permits bank holding companies to become financial holding companies and thereby affiliate with securities firms and insurance companies and engage in other activities that are financial in nature. The GLB Act defines “financial in nature” to include securities underwriting, dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and agency; merchant banking activities; and activities that the Federal Reserve has determined to be closely related to banking. No regulatory approval will be required for a financial holding company to acquire a company, other than a bank or savings association, engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the Federal Reserve. Safe and Sound Banking Practices. Bank holding companies are not permitted to engage in unsafe and unsound banking practices. The Federal Reserve’s Regulation Y, for example, generally requires a bank holding company to provide the Federal Reserve with prior notice of any redemption or repurchase of its own equity securities, if the consideration to be paid, together with the consideration paid for any repurchases or redemptions in the preceding year, is equal to 10% or more of the bank holding company’s consolidated net worth. The Federal Reserve may oppose the transaction if it believes that the transaction would constitute an unsafe or unsound practice or would violate any law or regulation. In certain circumstances, the Federal Reserve could take the position that paying a dividend would constitute an unsafe or unsound banking practice. The Federal Reserve has broad authority to prohibit activities of bank holding companies and their nonbanking subsidiaries which represent unsafe and unsound banking practices or which constitute violations of laws or regulations, and can assess civil money penalties for certain activities conducted on a knowing and reckless basis, if those activities caused a substantial loss to a depository institution. The penalties can be as high as one million dollars ($1,000,000) for each day the activity continues. Anti-Tying Restrictions. Bank holding companies and their affiliates are prohibited from tying the provision of certain services, such as extensions of credit, to other nonbanking services offered by a bank holding company or its affiliates. Capital Adequacy Requirements. The Federal Reserve has historically utilized a system based upon risk-based capital guidelines under a two-tier capital framework to evaluate the capital adequacy of bank holding companies. Tier 1 capital generally consists of common stockholders’ equity, retained earnings, a limited amount of qualifying perpetual preferred stock, qualifying trust preferred securities and noncontrolling interests in the equity accounts of consolidated subsidiaries, less goodwill and certain intangibles. Tier 2 capital generally consists of certain hybrid capital instruments and perpetual debt, mandatory convertible debt securities and a limited amount of subordinated debt, qualifying preferred stock, loan loss allowance, and unrealized holding gains on certain equity securities. The regulatory capital requirements are applicable to the Company because its total consolidated assets equal more than $1 billion. Independent Bank is subject to the capital requirements of the FDIC. Under the guidelines, specific categories of assets are assigned different risk weights, based generally on the perceived credit risk of the asset. These risk weights are multiplied by corresponding asset balances to determine a “risk-weighted” asset base. The guidelines require a minimum ratio of total capital to total risk-weighted assets of 8.0% (of which at least 4.0% is required to consist of Tier 1 capital elements). Total capital is the sum of Tier 1 and Tier 2 capital. Risk-weighted assets exclude intangible assets such as goodwill and core deposit intangibles. In addition to the risk-based capital guidelines, the Federal Reserve uses a leverage ratio as an additional tool to evaluate the capital adequacy of bank holding companies. The leverage ratio is a company’s Tier 1 capital divided by its average total consolidated assets. Certain highly rated bank holding companies may maintain a minimum leverage ratio of 3.0%, but other bank holding companies are required to maintain a leverage ratio of at least 4.0%. The federal banking agencies’ risk-based and leverage capital ratios are minimum supervisory ratios generally applicable to banking organizations that meet certain specified criteria. Banking organizations not meeting these criteria are expected to operate with capital positions well above the minimum ratios. The federal bank regulatory agencies may set capital requirements for a particular banking organization that are higher than the minimum ratios when circumstances warrant. Federal Reserve guidelines also provide that banking organizations experiencing internal growth or making acquisitions must maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets. On July 2, 2013, the Federal Reserve approved a final rule implementing the revised capital standards issued by the Basel Committee on Banking Supervision, commonly known as “Basel III,” as well as additional capital reforms required by the Dodd-Frank Act. This final rule, once fully phased-in, requires bank holding companies and their bank subsidiaries to maintain substantially more capital, with a greater emphasis on common equity. 6 The new final capital framework, among other things, (i) introduces as a new capital measure “Common Equity Tier 1,” or CET1, (ii) specifies that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (iii) defines CET1 narrowly by requiring that most adjustments to regulatory capital measures be made to CET1 and not to the other components of capital and (iv) expands the scope of the adjustments as compared to existing regulations. The new capital rule, when fully phased in, requires, among other things, a new common equity Tier 1 risk-based ratio with a minimum required ratio of 4.5% of total assets and an increase in the minimum required amount of Tier 1 capital from the current level of 4% of total assets to 6% of total risk weighted assets and the continuation of the requirement to maintain total capital of 8% of total risk-weighted assets. The Company became subject to the new capital rules on January 1, 2015. A number of changes in what constitutes regulatory capital compared to the rules in effect prior to January 1, 2015 are subject to transition periods. These changes include the phasing-out of certain instruments as qualifying capital. Mortgage servicing rights and deferred tax assets over designated percentages of CET1 are deducted from capital. In addition, Tier 1 capital includes accumulated other comprehensive income, which includes all unrealized gains and losses on available for sale debt and equity securities. However, because of our asset size, we were eligible for the one-time option of permanently opting out of the inclusion of unrealized gains and losses on available for sale debt and equity securities in our capital calculations. We elected this option. For purposes of determining risk-based capital, assets and certain off-balance sheet items are risk-weighted from 0% to 1,250%, depending on the risk characteristics of the asset or item. The new regulations make certain changes in the risk- weighting of assets to better reflect credit risk and other risk exposure compared to the earlier capital rules. These include a 150% risk weight (up from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential mortgage loans that are 90 days past due or otherwise in nonaccrual status; a 20% (up from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; and a 250% risk weight (up from 100%) for mortgage servicing rights and deferred tax assets that are not deducted from capital. In addition to the minimum CET1, Tier 1 and total risk-based capital ratios, the Company and the Bank must maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. The new capital conservation buffer requirement began on January 1, 2016 when a buffer greater than 0.625% of risk-weighted assets was required, which will increase each year until the buffer requirement is fully implemented on January 1, 2019. Under the FRB’s prompt corrective action standards, in order to be considered well-capitalized, the Bank must have a ratio of CET1 capital to risk-weighted assets of 6.5%, a ratio of Tier 1 capital to risk-weighted assets of 8%, a ratio of total capital to risk-weighted assets of 10%, and a leverage ratio of 5%; and must not be subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. In order to be considered adequately capitalized, an institution must have the minimum capital ratios described above. As of December 31, 2017, the Bank was “well-capitalized.” An institution that is not well capitalized is subject to certain restrictions on brokered deposits and interest rates on deposits. Dodd-Frank Stress Testing. The Dodd-Frank Act and regulations issued by the Federal Reserve require that financial institutions with consolidated assets of greater than $10 billion evaluate and support their capital position under baseline, adverse, and severely adverse scenarios on an annual basis. These scenarios are created by banking regulatory agencies and include a wide array of macro-economic conditions. The goal of stress testing is to provide bank regulatory agencies with forward looking information to assist in the supervision and planning process regarding a bank’s risk profile and capital adequacy. Dodd-Frank Stress Testing requires a significant amount of data gathering and analysis and development of financial forecasting models. The Company has initiated a planning process to prepare for the Dodd-Frank Stress Testing requirements in anticipation of crossing the $10 billion threshold. Interchange Fees. The Durbin Amendment to the Dodd-Frank Act limits the amount of interchange fees that banks with assets of $10 billion or more may charge to process electronic debit transactions. The Company is monitoring developments with respect to the Durbin Amendment and is otherwise analyzing its potential impact on operations in anticipation of crossing the $10 billion threshold. Imposition of Liability for Undercapitalized Subsidiaries. Bank regulators are required to take prompt corrective action to resolve problems associated with insured depository institutions whose capital declines below certain levels. In the event an 7 institution becomes undercapitalized, it must submit a capital restoration plan. The capital restoration plan will not be accepted by the regulators unless each company having control of the undercapitalized institution guarantees the subsidiary’s compliance with the capital restoration plan up to a certain specified amount. Any such guarantee from a depository institution’s holding company is entitled to a priority of payment in bankruptcy. The aggregate liability of the holding company of an undercapitalized bank is limited to the lesser of 5.0% of the institution’s assets at the time it became undercapitalized or the amount necessary to cause the institution to be adequately capitalized. The bank regulators have greater power in situations where an institution becomes significantly or critically undercapitalized or fails to submit a capital restoration plan. For example, a bank holding company controlling such an institution can be required to obtain prior Federal Reserve approval of proposed dividends, or might be required to consent to a consolidation or to divest the troubled institution or other affiliates. Acquisitions by Bank Holding Companies. The BHC Act requires every bank holding company to obtain the prior approval of the Federal Reserve before it acquires all or substantially all of the assets of any bank, or ownership or control of any voting shares of any bank if after such acquisition it would own or control, directly or indirectly, more than 5% of the voting shares of such bank. In approving bank acquisitions by bank holding companies, the Federal Reserve is required to consider, among other things, the effect of the acquisition on competition, the financial condition, managerial resources and future prospects of the bank holding company and the banks concerned, the convenience and needs of the communities to be served (including the record of performance under the Community Reinvestment Act, or CRA), the effectiveness of the applicant in combating money laundering activities and the extent to which the proposed acquisition would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. The Company’s ability to make future acquisitions will depend on its ability to obtain approval for such acquisitions from the Federal Reserve. The Federal Reserve could deny the Company’s application based on the above criteria or other considerations. For example, the Company could be required to sell banking centers as a condition to receiving regulatory approval, which condition may not be acceptable to the Company or, if acceptable, may reduce the benefit of a proposed acquisition. Control Acquisitions. Federal and state laws, including the BHCA and the Change in Bank Control Act, or the CBCA, impose additional prior notice or approval requirements and ongoing regulatory requirements on any investor that seeks to acquire direct or indirect “control” of an FDIC-insured depository institution or bank holding company. Whether an investor “controls” a depository institution is based on all of the facts and circumstances surrounding the investment. As a general matter, an investor is deemed to control a depository institution or other company if the investor owns or controls 25% or more of any class of voting securities. Subject to rebuttal, an investor is presumed to control a depository institution or other company if the investor owns or controls 10% or more of any class of voting securities and either the depository institution or company is a public company or no other person will hold a greater percentage of that class of voting securities after the acquisition. If an investor’s ownership of the Company’s voting securities were to exceed certain thresholds, the investor could be deemed to “control” the Company for regulatory purposes, which could subject such investor to regulatory filings or other regulatory consequences. Federal Securities Laws. The common stock of the Company is registered with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Therefore, the Company is subject to the reporting, information disclosure, proxy solicitation, insider trading limits and other requirements imposed on public companies by the SEC under the Exchange Act. This includes limits on sales of stock by certain insiders and the filing of insider ownership reports with the SEC. The SEC and Nasdaq have adopted regulations under the Sarbanes-Oxley Act of 2002 and the Dodd Frank Act that apply to the Company as a Nasdaq-traded, public company, which seek to improve corporate governance, provide enhanced penalties for financial reporting improprieties and improve the reliability of disclosures in SEC filings. Regulation of Independent Bank Independent Bank is a Texas-chartered banking association, the deposits of which are insured by the deposit insurance fund of the FDIC. Independent Bank is not a member of the Federal Reserve System; therefore, Independent Bank is subject to supervision and regulation by the FDIC and the TDB. Such supervision and regulation subject Independent Bank to special restrictions, requirements, potential enforcement actions and periodic examination by the FDIC and the TDB. Because the Federal Reserve regulates the Company, the Federal Reserve also has supervisory authority that directly affects Independent Bank. Equivalence to National Bank Powers. The Texas Constitution, as amended in 1986, provides that a Texas-chartered bank has the same rights and privileges that are or may be granted to national banks domiciled in Texas. To the extent that the Texas laws and regulations may have allowed state-chartered banks to engage in a broader range of activities than national banks, the Federal Deposit Insurance Corporation Improvement Act of 1991, or the FDICIA, has operated to limit this authority. The 8 FDICIA provides that no state bank or subsidiary thereof may engage as a principal in any activity not permitted for national banks, unless the institution complies with applicable capital requirements and the FDIC determines that the activity poses no significant risk to the deposit insurance fund of the FDIC. In general, statutory restrictions on the activities of banks are aimed at protecting the safety and soundness of depository institutions. Financial Modernization. Under the GLB Act, a national bank may establish a financial subsidiary and engage, subject to limitations on investment, in activities that are financial in nature, other than insurance underwriting as principal, insurance company portfolio investment, real estate development, real estate investment, annuity issuance and merchant banking activities. To do so, a bank must be well capitalized, well managed and have a Community Reinvestment Act, or CRA, rating from the FDIC of satisfactory or better. Subsidiary banks of a financial holding company or national banks with financial subsidiaries must remain well capitalized and well managed in order to continue to engage in activities that are financial in nature without regulatory actions or restrictions. Such actions or restrictions could include divestiture of the “financial in nature” subsidiary or subsidiaries. In addition, a financial holding company or a bank may not acquire a company that is engaged in activities that are financial in nature unless each of the subsidiary banks of the financial holding company or the bank has a CRA rating of satisfactory of better. Although the powers of state chartered banks are not specifically addressed in the GLB Act, Texas- chartered banks such as Independent Bank will have the same if not greater powers as national banks through the parity provisions contained in the Texas Constitution and other Texas statutes. Branching. Texas law provides that a Texas-chartered bank can establish a branch anywhere in Texas provided that the branch is approved in advance by the TDB. The branch must also be approved by the FDIC, which considers a number of factors, including financial history, capital adequacy, earnings prospects, character of management, needs of the community and consistency with corporate powers. The Dodd-Frank Act permits insured state banks to engage in de novo interstate branching if the laws of the state where the new branch is to be established would permit the establishment of the branch if it were chartered by such state. Restrictions on Transactions with Affiliates and Insiders. Transactions between Independent Bank and its nonbanking subsidiaries and/or affiliates, including the Company, are subject to Section 23A of the Federal Reserve Act. In general, Section 23A of the Federal Reserve Act imposes limits on the amount of such transactions, and also requires certain levels of collateral for loans to affiliated parties. It also limits the amount of advances to third parties that are collateralized by the securities or obligations of the Company or its subsidiaries. Covered transactions with any single affiliate may not exceed 10% of the capital stock and surplus of Independent Bank, and covered transactions with all affiliates may not exceed, in the aggregate, 20% of Independent Bank’s capital and surplus. For a bank, capital stock and surplus refers to the bank’s Tier 1 and Tier 2 capital, as calculated under the risk-based capital guidelines, plus the balance of the allowance for credit losses excluded from Tier 2 capital. Independent Bank’s transactions with all of its affiliates in the aggregate are limited to 20% of the foregoing capital. “Covered transactions” are defined by statute to include a loan or extension of credit to an affiliate, as well as a purchase of securities issued by an affiliate, a purchase of assets (unless otherwise exempted by the Federal Reserve) from the affiliate, the acceptance of securities issued by the affiliate as collateral for a loan, and the issuance of a guarantee, acceptance or letter of credit on behalf of an affiliate. In addition, in connection with covered transactions that are extensions of credit, Independent Bank may be required to hold collateral to provide added security to Independent Bank, and the types of permissible collateral may be limited. The Dodd-Frank Act generally enhances the restrictions on transactions with affiliates. Affiliate transactions are also subject to Section 23B of the Federal Reserve Act, which generally requires that certain transactions between Independent Bank and its affiliates be on terms substantially the same, or at least as favorable to Independent Bank, as those prevailing at the time for comparable transactions with or involving other nonaffiliated persons. The restrictions on loans to directors, executive officers, principal shareholders and their related interests (collectively referred to herein as “insiders”) contained in the Federal Reserve Act and in Regulation O promulgated by the Federal Reserve apply to all insured institutions and their subsidiaries and bank holding companies. These restrictions include limits on loans to one borrower and conditions that must be met before such a loan can be made. There is also an aggregate limitation on all loans to insiders and their related interests. Generally, these loans cannot exceed the institution’s total unimpaired capital and surplus, and the FDIC may determine that a lesser amount is appropriate. Loans to senior executive officers of a bank are even further restricted, generally limited to $100,000 per senior executive officer. Insiders are subject to enforcement actions for knowingly accepting loans in violation of applicable restrictions. Restrictions on Dividends. Dividends paid by Independent Bank have provided a substantial part of the Company’s operating funds, and for the foreseeable future, it is anticipated that dividends paid by Independent Bank to the Company will continue to be the Company’s principal source of operating funds. However, capital adequacy requirements serve to limit the amount of 9 dividends that may be paid by Independent Bank. Under federal law, Independent Bank cannot pay a dividend if, after paying the dividend, it would be undercapitalized. The FDIC may declare a dividend payment to be unsafe and unsound even though Independent Bank would continue to meet its capital requirements after payment of the dividend. Because the Company is a legal entity separate and distinct from its subsidiaries, its right to participate in the distribution of assets of any subsidiary upon the subsidiary’s liquidation or reorganization will be subject to the prior claims of the subsidiary’s creditors. The Federal Deposit Insurance Act, or the FDI Act, provides that, in the event of a “liquidation or other resolution” of an insured depository institution, the claims of depositors of the institution (including the claims of the FDIC as subrogee of insured depositors) and certain claims for administrative expenses of the FDIC as a receiver will have priority over other general unsecured claims against the institution. If Independent Bank fails, insured and uninsured depositors, along with the FDIC, will have priority in payment ahead of unsecured, nondeposit creditors, including the Company, with respect to any extensions of credit it has made to Independent Bank. Examinations. The FDIC periodically examines and evaluates state nonmember banks. Based on such an evaluation, the FDIC may revalue the assets of the institution and require that it establish specific reserves to compensate for the difference between the FDIC determined value and the book value of such assets. The TDB also conducts examinations of state banks, but may accept the results of a federal examination in lieu of conducting an independent examination. In addition, the FDIC and TDB may elect to conduct a joint examination. Audit Reports. Insured institutions with total assets of $500 million or more must submit annual audit reports prepared by independent auditors to federal and state regulators. In some instances, the audit report of the institution’s holding company can be used to satisfy this requirement. Auditors of an insured institution must receive examination reports, supervisory agreements and reports of enforcement actions. For institutions with total assets of $1 billion or more, financial statements prepared in accordance with GAAP, management’s certifications signed by the Company’s and Independent Bank’s chief executive officer and chief accounting or financial officer concerning management’s responsibility for the financial statements, and an attestation by the auditors regarding Independent Bank’s internal controls must also be submitted. For institutions with total assets of more than $3 billion, independent auditors may be required to review quarterly financial statements. The FDICIA requires that Independent Bank have an independent audit committee, consisting only of outside directors, or that the Company has an audit committee that is entirely independent. The committees of such institutions must include members with experience in banking or financial management, must have access to outside counsel, and must not include representatives of large customers. Capital Adequacy Requirements. The FDIC has adopted regulations establishing minimum requirements for the capital adequacy of insured institutions and may establish higher minimum requirements if, for example, a bank has previously received special attention or has a high susceptibility to interest rate risk. The FDIC’s risk-based capital guidelines generally require state banks to have a minimum ratio of Tier 1 capital to total risk-weighted assets of 4.0% and a ratio of total capital to total risk-weighted assets of 8.0%. The capital categories have the same definitions for Independent Bank as for the Company. The FDIC’s leverage guidelines require state banks to maintain Tier 1 capital of no less than 4.0% of average total assets, except in the case of certain highly rated banks for which the requirement is 3.0% of average total assets. The TDB has issued a policy which generally requires state chartered banks to maintain a leverage ratio (defined in accordance with federal capital guidelines) of 5.0%. Corrective Measures for Capital Deficiencies. The federal banking regulators are required by the FDI Act to take “prompt corrective action” with respect to capital-deficient institutions that are FDIC-insured. Agency regulations define, for each capital category, the levels at which institutions are “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized.” A “well capitalized” bank has a total risk-based capital ratio of 10.0% or higher, a Tier 1 risk-based capital ratio of 6.0% or higher, a leverage ratio of 5.0% or higher, and is not subject to any written agreement, order or directive requiring it to maintain a specific capital level for any capital measure. An “adequately capitalized” bank has a total risk-based capital ratio of 8.0% or higher, a Tier 1 risk-based capital ratio of 4.0% or higher, a leverage ratio of 4.0% or higher (3.0% or higher if the bank was rated a composite 1 in its most recent examination report and is not experiencing significant growth), and does not meet the criteria for a well‑capitalized bank. A bank is “undercapitalized” if it fails to meet any one of the ratios required to be adequately capitalized. In addition to requiring undercapitalized institutions to submit a capital restoration plan, agency regulations contain broad restrictions on certain activities of undercapitalized institutions, including asset growth, acquisitions, branch establishment and expansion into new lines of business. With certain exceptions, an insured depository institution is prohibited from making capital distributions, including dividends, and is prohibited from paying management fees to control persons if the institution would be undercapitalized after any such distribution or payment. 10 As an institution’s capital decreases, the FDIC’s enforcement powers become more severe. A significantly undercapitalized institution is subject to mandated capital raising activities, restrictions on interest rates paid and transactions with affiliates, removal of management and other restrictions. The FDIC has only very limited discretion in dealing with a critically undercapitalized institution and is virtually required to appoint a receiver or conservator. Banks with risk-based capital and leverage ratios below the required minimums may also be subject to certain administrative actions, including the termination of deposit insurance upon notice and hearing, or a temporary suspension of insurance without a hearing in the event the institution has no tangible capital. Deposit Insurance Assessments. Substantially all of the deposits of Independent Bank are insured up to applicable limits by the deposit insurance fund of the FDIC, and Independent Bank must pay annual deposit insurance assessments to the FDIC for such deposit insurance protection. The FDIC maintains the deposit insurance fund by designating a required reserve ratio. If the reserve ratio falls below the designated level, the FDIC must adopt a restoration plan that provides that the deposit insurance fund will return to an acceptable level generally within five years. On December 20, 2010, the FDIC raised the minimum designated reserve ratio of the deposit insurance fund to 2.00%, which exceeds the 1.35% reserve ratio that is required by the Dodd-Frank Act. The FDIC has the discretion to set the price for deposit insurance according to the risk for all insured institutions regardless of the level of the reserve ratio. Under the Dodd-Frank Act, the FDIC is required to offset the effect of the higher reserve ratio on small insured depository institutions, which are those with consolidated assets of less than $10 billion. The deposit insurance fund reserve ratio is maintained by assessing depository institutions and establishing an insurance premium based upon statutory factors. Under its current regulations, the FDIC imposes assessments for deposit insurance according to a depository institution’s ranking in one of four risk categories based upon supervisory and capital evaluations. On February 7, 2012, the FDIC approved a final rule that amends its existing deposit insurance funds restoration plan and implements certain provisions of the Dodd-Frank Act. Effective as of July 1, 2012, the assessment base is determined using average consolidated total assets minus average tangible equity rather than the current assessment base of adjusted domestic deposits. Because the change resulted in a much larger assessment base, the final rule also lowered the assessment rates in order to keep the total amount collected from financial institutions relatively unchanged from the amounts previously being collected. After the effect of potential base-rate adjustments, the total base assessment rate for Independent Bank could range from 2.5 to 45 basis points on an annualized basis. Brokered Deposit Restrictions. Adequately capitalized institutions cannot accept, renew or roll over brokered deposits, without receiving a waiver from the FDIC, and are subject to restrictions on the interest rates that can be paid on any deposits. Undercapitalized institutions may not accept, renew or roll over brokered deposits. Concentrated Commercial Real Estate Lending Regulations. The federal banking agencies have promulgated guidance governing financial institutions with concentrations in commercial real estate lending. The guidance provides that a bank has a concentration in commercial real estate lending if (i) total reported loans for construction, land development and other land represent 100% or more of total capital or (ii) total reported loans secured by multifamily and nonfarm residential properties and loans for construction, land development and other land represent 300% or more of total capital and the bank’s commercial real estate loan portfolio has increased 50% or more during the prior 36 months. Owner occupied loans are excluded from this second category. If a concentration is present, management must employ heightened risk management practices that address the following key elements: board and management oversight and strategic planning, portfolio management, development of underwriting standards, risk assessment and monitoring through market analysis and stress testing, and maintenance of increased capital levels as needed to support the level of commercial real estate lending. Cross-Guarantee Provisions. The Financial Institutions Reform, Recovery and Enforcement Act of 1989, or the FIRREA, contains a “cross-guarantee” provision, which generally makes commonly controlled insured depository institutions liable to the FDIC for any losses incurred in connection with the failure of a commonly controlled depository institution. Community Reinvestment Act. The CRA and the regulations issued thereunder are intended to encourage banks to help meet the credit needs of their entire service area, including low and moderate income neighborhoods, consistent with the safe and sound operations of such banks. These regulations also provide for regulatory assessment of a bank’s record in meeting the needs of its service area when considering applications to establish branches, merger applications and applications to acquire the assets and assume the liabilities of another bank. The FIRREA requires federal banking agencies to make public a rating of a bank’s performance under the CRA. In the case of a bank holding company, the CRA performance record of the banks involved in the transaction are reviewed in connection with the filing of an application to acquire ownership or control of 11 shares or assets of a bank or to merge with any other bank holding company. An unsatisfactory CRA record could substantially delay approval or result in denial of an application. Consumer Laws and Regulations. In addition to the laws and regulations discussed herein, Independent Bank is also subject to certain consumer laws and regulations that are designed to protect consumers in transactions with banks. While the list set forth herein is not exhaustive, these laws and regulations include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, and the Fair Housing Act, among others. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits or making loans to such customers. Independent Bank must comply with the applicable provisions of these consumer protection laws and regulations as part of their ongoing customer relations. The Dodd-Frank Act created a new independent Consumer Financial Protection Bureau, which has broad authority to regulate and supervise retail financial services activities of banks, such as Independent Bank, and has the authority to promulgate regulations, issue orders, guidance and policy statements, conduct examinations and bring enforcement actions with regard to consumer financial products and services. In general, however, banks with assets of $10 billion or less, such as Independent Bank, will continue to be examined for consumer compliance by their primary bank regulator. Privacy. In addition to expanding the activities in which banks and bank holding companies may engage, the GLB Act also imposed new requirements on financial institutions with respect to customer privacy. The GLB Act generally prohibits disclosure of customer information to nonaffiliated third parties unless the customer has been given the opportunity to object and has not objected to such disclosure. Financial institutions are further required to disclose their privacy policies to customers annually. Financial institutions, however, are required to comply with state law if it is more protective of customer privacy than the GLB Act. Anti-Money Laundering and Anti-Terrorism Legislation. A major focus of governmental policy on financial institutions in recent years has been aimed at combating money laundering and terrorist financing. The USA PATRIOT Act of 2001, or the USA Patriot Act, substantially broadened the scope of U.S. anti-money laundering laws and regulations by imposing significant new compliance and due diligence obligations, creating new crimes and penalties and expanding the extra-territorial jurisdiction of the United States. The U.S. Treasury Department has issued and, in some cases, proposed a number of regulations that apply various requirements of the USA Patriot Act to financial institutions. These regulations impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identity of their customers. The USA Patriot Act requires, among other things, financial institutions to comply with certain due diligence requirements in connection with correspondent or private banking relationships with non-U.S. financial institutions or persons, establish an anti-money laundering program that includes employee training and an independent audit, follow minimum standards for identifying customers and maintaining records of the identification information and make regular comparisons of customers against agency lists of suspected terrorists, their organizations and money launderers. Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with all of the relevant laws or regulations, could have serious legal and reputational consequences for the institution. Office of Foreign Assets Control Regulation. The United States has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. These are typically known as the “OFAC” rules based on their administration by the U.S. Treasury Department Office of Foreign Assets Control, or OFAC. The OFAC-administered sanctions targeting certain countries take many different forms. Generally, however, they contain one or more of the following elements: (i) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on “U.S. persons” engaging in financial transactions relating to making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (ii) a blocking of assets in which the government or specially designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to a U.S. jurisdiction (including property in the possession or control of U.S. persons). Blocked assets (e.g., property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences. Changes in Laws, Regulations or Policies In general, regulators have increased their focus on the regulation of financial institutions. From time to time, various legislative and regulatory initiatives are introduced in Congress and state legislatures. Such initiatives may change banking statutes and the operating environment of the Company and Independent Bank in substantial and unpredictable ways. The Company cannot determine the ultimate effect that any potential legislation, if enacted, or implementing regulations with respect thereto, would have, upon the financial condition or results of operations of the Company or Independent Bank. A 12 change in statutes, regulations or regulatory policies applicable to the Company or Independent Bank could have a material effect on the financial condition, results of operations or business of the Company and Independent Bank. Enforcement Powers of Federal and State Banking Agencies The federal banking agencies have broad enforcement powers, including the power to terminate deposit insurance, impose substantial fines and other civil and criminal penalties, and appoint a conservator or receiver. Failure to comply with applicable laws, regulations and supervisory agreements could subject the Company or Independent Bank and their subsidiaries, as well as their respective officers, directors, and other institution‑affiliated parties, to administrative sanctions and potentially substantial civil money penalties. In addition to the grounds discussed above under “Corrective Measures for Capital Deficiencies,” the appropriate federal banking agency may appoint the FDIC as conservator or receiver for a banking institution (or the FDIC may appoint itself, under certain circumstances) if any one or more of a number of circumstances exist. The TDB also has broad enforcement powers over Independent Bank, including the power to impose orders, remove officers and directors, impose fines and appoint supervisors and conservators. Effect on Economic Environment The policies of regulatory authorities, including the monetary policy of the Federal Reserve, have a significant effect on the operating results of bank holding companies and their subsidiaries. Among the means available to the Federal Reserve to affect the money supply are open market operations in U.S. government securities, changes in the discount rate on member bank borrowings, and changes in reserve requirements against member bank deposits. These means are used in varying combinations to influence overall growth and distribution of bank loans, investments and deposits, and their use may affect interest rates charged on loans or paid for deposits. Federal Reserve monetary policies have materially affected the operating results of commercial banks in the past and are expected to continue to do so in the future. The Company cannot predict the nature of future monetary policies and the effect of such policies on the business and earnings of it and its subsidiaries. 13 ITEM 1A. RISK FACTORS An investment in the Company’s common stock involves risks. The following is a description of the material risks and uncertainties that the Company believes affect its business and an investment in the common stock. Additional risks and uncertainties that the Company is unaware of, or that it currently deems immaterial, also may become important factors that affect the Company and its business. If any of the risks described in this Annual Report on Form 10-K were to occur, the Company’s financial condition, results of operations and cash flows could be materially and adversely affected. If this were to happen, the value of the common stock could decline significantly and you could lose all or part of your investment. Risks Related to the Company’s Business The Company’s success depends significantly on the Company’s management team, and the loss of the Company’s senior executive officers or other key employees and the Company’s inability to recruit or retain suitable replacements could adversely affect the Company’s business, results of operations and growth prospects. The Company’s success depends significantly on the continued service and skills of the Company’s existing executive management team. The implementation of the Company’s business and growth strategies also depends significantly on the Company’s ability to retain officers and employees with experience and business relationships within their respective market areas. The Company’s ability to attract and retain key employees is dependent upon its compensation and benefits programs, continued growth and profitability, and reputation for rewarding and promoting qualified employees. The cost of employee compensation constitutes a significant portion of the Company’s non-interest expense and can materially impact results of operations. The Company could have difficulty replacing departed officers and employees with persons who are experienced in the specialized aspects of the Company’s business or who have ties to the communities within the Company’s market areas. The unexpected loss of any of the Company’s key personnel could therefore have an adverse impact on the Company’s business and growth. The Company’s continued success is dependent upon the ability of its executive management and the development of an appropriate succession plan for key officers. Volatile market conditions and economic trends could adversely affect the Company’s business, financial condition and results of operations. The Company is operating in a dynamic and challenging economic environment, including uncertain global, national and local market conditions. In particular, Texas and Colorado based financial institutions are affected by volatility in the energy markets and the potential impact of that volatility on real estate and other markets. The Company is also subject to uncertain interest rate conditions. These volatile economic conditions could adversely affect borrowers and their businesses as well as the value of collateral (particularly real estate collateral) securing loans, which could adversely affect the Company’s business, financial condition and results of operation. The Company’s business concentration in Texas and Colorado imposes risks and may magnify the adverse effects and consequences to the Company resulting from any regional or local economic downturn affecting Texas and Colorado. The Company conducts its operations almost exclusively in Texas and Colorado. This geographic concentration imposes risks from lack of geographic diversification. The economic conditions in Texas affect the Company’s business, financial condition, results of operations, and future prospects, where adverse economic developments, among other things, could affect the volume of loan originations, increase the level of nonperforming assets, increase the rate of foreclosure losses on loans and reduce the value of the Company’s loans and loan servicing portfolio. Moreover, if the population or income growth in the Company’s market areas is slower than projected, income levels, deposits and housing starts could be adversely affected and could result in a reduction of the Company’s expansion, growth and profitability. While the Texas economy is more diversified than in the past, the energy sector has had, and is expected to continue to have, a significant impact on the overall Texas economy. Any regional or local economic downturn that affects Texas or Colorado, or existing or prospective borrowers or property values in such areas, may affect the Company and the Company’s profitability more significantly and more adversely than the Company’s competitors whose operations are less geographically concentrated. 14 If the Company does not effectively manage the Company’s asset quality and credit risk, the Company would experience loan losses, which could have a material adverse effect on the Company’s financial condition and results of operation. Making any loan involves risk, including risks inherent in dealing with individual borrowers, risks of nonpayment, risks resulting from uncertainties as to the future value of collateral and cash flows available to service debt, and risks resulting from changes in economic and market conditions. The Company’s credit risk approval and monitoring procedures may fail to identify or reduce these credit risks, and they cannot completely eliminate all credit risks related to the Company’s loan portfolio. The Company faces a variety of risk related to its types of loans. Adverse developments affecting commercial real estate values in the Company’s market areas could increase the credit risk associated with commercial real estate loans, impair the value of the property pledged as collateral for these loans, and affect the Company’s ability to sell the collateral upon foreclosure without a loss. Further, due to the larger average size of commercial real estate loans, the Company faces risk that losses incurred on a small number of commercial real estate loans could have a material adverse effect on the Company’s financial condition and results of operations. The Company’s commercial real estate loans also have the risk that repayment is subject to the ongoing business operations of the borrower. The Company’s commercial loans also have the risk that repayment is subject to the ongoing business operations of the borrower. Commercial loans are often secured by personal property, such as inventory, and intangible property, such as accounts receivable, which if the business is unsuccessful, typically have values insufficient to satisfy the loan without a loss. If the overall economic climate in the United States, generally, or the Company’s market areas in Texas, specifically, experiences material disruption, the Company’s borrowers may experience difficulties in repaying their loans, the collateral the Company holds may decrease in value or become illiquid, and the level of nonperforming loans, charge-offs and delinquencies could rise and require additional provisions for loan losses, which would cause the Company’s net income and return on equity to decrease. Negative changes in the economy affecting real estate values and liquidity, and business operating conditions generally, could impair the repayment ability of borrowers and the value of collateral securing the Company’s loans which would result in loan and other losses. As of December 31, 2017, approximately 82% of the Company’s loan portfolio was comprised of loans with real estate as a primary or secondary component of collateral, excluding agricultural loans secured by real estate. As a result, adverse developments affecting real estate values in the Company’s market areas could increase the credit risk associated with the Company’s real estate loan portfolio. The market value of real estate can fluctuate significantly in a short period of time as a result of market conditions in the area in which the real estate is located. Adverse changes affecting real estate values and the liquidity of real estate in one or more of the Company’s markets could increase the credit risk associated with the Company’s loan portfolio, and could result in losses that would adversely affect credit quality, financial condition, and results of operation. Negative changes in the economy affecting real estate values and liquidity in the Company’s market areas could significantly impair the value of property pledged as collateral on loans and affect the Company’s ability to sell the collateral upon foreclosure without a loss or additional losses. Collateral may have to be sold for less than the outstanding balance of the loan, which could result in losses on such loans. Such declines and losses would have a material adverse impact on the Company’s business, results of operations and growth prospects. If real estate values decline, it is also more likely that the Company would be required to increase the Company’s allowance for loan losses, which could adversely affect the Company’s financial condition, results of operations and cash flows. Adverse developments in the energy industry could have a negative effect on the Company’s asset quality. As of December 31, 2017, approximately 1.7% of the Company’s loan portfolio was composed of loans made to companies engaged in oil production and oilfield services. The significant decline in oil prices during 2015 adversely effected some of these borrowers’ ability to repay these loans and impaired the value of collateral securing some of these loans. The Company experienced an increase in non-performing assets and loan loss provisions in 2015 and early 2016 primarily due to energy loans. Further, because energy is a material segment of the overall Texas economy, the decline and volatility in oil prices could have an impact on other segments of the Texas economy, including real estate. The Houston market economy in particular could be adversely affected. The Company’s asset quality and results of operations could be adversely impacted by the direct and indirect effects of current and future conditions in the Texas energy industry. The Company’s small to medium-sized business customers may have fewer financial resources than larger entities to weather a downturn in the economy, which may impair a borrower’s ability to repay a loan, and such impairment could adversely affect the Company’s results of operations and financial condition. The Company focuses its business development and marketing strategy primarily to serve the banking and financial services needs of small to medium-sized businesses. These small to medium-sized businesses generally have fewer financial resources 15 in terms of capital or borrowing capacity than larger entities. If general economic conditions negatively impact the Dallas/North Texas, Austin/Central Texas, Houston and Colorado market areas in which the Company operates or the Texas or Colorado market generally and small to medium-sized businesses are adversely affected, the Company’s results of operations and financial condition may be negatively affected. The Company’s allowance for loan losses may prove to be insufficient to absorb potential losses in the Company’s loan portfolio, which may adversely affect the Company’s business, financial condition and results of operations. The Company establishes its allowance for loan losses and maintains it at a level considered adequate by management to absorb probable loan losses based on the Company’s analysis of its portfolio and market environment. The allowance for loan losses represents the Company’s estimate of probable losses in the portfolio at each balance sheet date and is based upon relevant information available to the Company. The allowance contains provisions for probable losses that have been identified relating to specific borrowing relationships, as well as probable losses inherent in the loan portfolio and credit undertakings that are not specifically identified. Additions to the allowance for loan losses, which are charged to earnings through the provision for loan losses, are determined based on a variety of factors, including an analysis of the loan portfolio, historical loss experience and an evaluation of current economic conditions in the Company’s market areas. The actual amount of loan losses is affected by changes in economic, operating and other conditions within the Company’s markets, as well as changes in the financial condition, cash flows, and operations of the Company’s borrowers, all of which are beyond the Company’s control, and such losses may exceed current estimates. As of December 31, 2017, the Company’s allowance for loan losses as a percentage of total loans was 0.62% and as a percentage of total nonperforming loans was 255.62%. Additional loan losses will likely occur in the future and may occur at a rate greater than the Company has previously experienced. The Company may be required to take additional provisions for loan losses in the future to further supplement the allowance for loan losses, either due to management’s decision to do so or requirements by the Company’s banking regulators. In addition, bank regulatory agencies will periodically review the Company’s allowance for loan losses and the value attributed to nonaccrual loans or to real estate acquired through foreclosure. Such regulatory agencies may require the Company to recognize future charge-offs. These adjustments may adversely affect the Company’s business, financial condition and results of operations. If the Company is not able to continue its historical levels of growth, it may not be able to maintain its historical earnings trends. To achieve its past levels of growth, the Company has focused on both internal growth and acquisitions. The Company may not be able to sustain its historical rate of growth or may not be able to grow at all. More specifically, the Company may not be able to obtain the financing necessary to fund additional growth and may not be able to find suitable acquisition candidates. Various factors, such as economic conditions and competition, may impede or prohibit the opening of new banking centers and the completion of acquisitions. Further, the Company may be unable to attract and retain experienced bankers, which could adversely affect its internal growth. If the Company is not able to continue its historical levels of growth, it may not be able to maintain its historical earnings trends. The Company’s strategy of pursuing acquisitions exposes the Company to financial, execution and operational risks that could have a material adverse effect on the Company’s business, financial condition, results of operations and growth prospects. The Company has been pursuing a growth strategy that includes the acquisition of other financial institutions in target markets. The Company has completed ten acquisitions since 2010, most recently completing the Carlile Bancshares, Inc. acquisition on April 1, 2017. In addition, the Company announced the acquisition of Integrity Bancshares, Inc. (“Integrity”) on November 28, 2017 and, absent delays, expects to close the Integrity acquisition during the second quarter of 2018. The Company intends to continue its acquisition strategy. Such an acquisition strategy, involves significant risks, including the following: finding suitable markets for expansion; finding suitable candidates for acquisition; attracting funding to support additional growth; • • • • maintaining asset quality; • • maintaining adequate regulatory capital. attracting and retaining qualified management; and Accordingly, the Company may be unable to find suitable acquisition candidates in the future that fit its acquisition and growth strategy. 16 Acquisitions of financial institutions also involve operational risks and uncertainties, and acquired companies may have unknown or contingent liabilities with no available manner of recourse, exposure to unexpected asset quality problems, key employee and customer retention problems and other problems that could negatively affect the Company’s organization. The Company may not be able to complete future acquisitions or, if completed, the Company may not be able to successfully integrate the operations, management, products and services of the entities that the Company acquires and eliminate redundancies. The integration process may also require significant time and attention from the Company’s management that they would otherwise direct toward servicing existing business and developing new business. Further, the integration process could result in the loss of key employees, disruption of the combined entity’s ongoing business, or inconsistencies in standards, controls, procedures and policies that adversely affect the Company’s ability to maintain relationships with customers or employees or to achieve the anticipated benefits of the transaction. Failure to successfully integrate the entities the Company acquires into the Company’s existing operations may increase the Company’s operating costs significantly and adversely affect the Company’s business and earnings. Acquisitions typically involve the payment of a premium over book and market values and, therefore, some dilution of the Company’s tangible book value and net income per common share may occur in connection with any future transaction. If the Company does not manage the Company’s growth effectively, the Company’s business, financial condition, results of operations and future prospects could be negatively affected, and the Company may not be able to continue to implement the Company’s business strategy and successfully conduct the Company’s operations. The Company’s proposed acquisition of Integrity may not be completed. Completion of the acquisition of Integrity is subject to a number of conditions precedent, including shareholder and regulatory approval, as well as satisfaction of certain financial requirements applicable to Integrity. If the conditions precedent are not satisfied, or waived, the transaction would not be consummated. Integrating Integrity Bank into Independent Bank’s operations may be more difficult, costly or time-consuming than the Company expects. Independent Bank and Integrity Bank have operated and, until the merger is completed, will continue to operate, independently. Accordingly, the process of integrating Integrity Bank’s operations into Independent Bank’s operations could result in the disruption of operations, the loss of Integrity Bank customers and employees and make it more difficult to achieve the intended benefits of the merger. Inconsistencies between the standards, controls, procedures and policies of Independent Bank and those of Integrity Bank could adversely affect Independent Bank’s ability to maintain relationships with current customers and employees of Integrity Bank if and when the merger is completed. As with any merger of banking institutions, business disruptions may occur that may cause Independent Bank to lose customers or may cause Integrity Bank’s customers to withdraw their deposits from Integrity Bank prior to the merger’s consummation and from Independent Bank thereafter. The realization of the anticipated benefits of the merger may depend in large part on Independent’s ability to integrate Integrity Bank‘s operations into Independent Bank’s operations, and to address differences in business models and cultures. If the Company is unable to integrate the operations of Integrity and Integrity Bank into the Company’s and Independent Bank’s operations successfully and on a timely basis, some or all of the expected benefits of the merger may not be realized. Difficulties encountered with respect to such matters could result in an adverse effect on the financial condition, results of operations, capital, liquidity or cash flows of Independent Bank and the Company. The Company may fail to realize the cost savings anticipated from the merger. Although the Company anticipates that it would realize certain cost savings as to the operations of Integrity and Integrity Bank and otherwise from the merger if and when the operations of Integrity and Integrity Bank are fully integrated in the Company’s and Independent Bank’s operations, it is possible that the Company may not realize all of the cost savings that the Company has estimated it can realize from the merger. For example, for a variety of reasons, the Company may be required to continue to operate or maintain some facilities or support functions that are currently expected to be combined or reduced as a result of the merger. The Company’s realization of the estimated cost savings also will depend on the Company’s ability to combine the operations of the Company and Independent Bank with the operations of Integrity and Integrity Bank in a manner that permits those costs savings to be realized. If the Company is not able to integrate the operations of Integrity and Integrity Bank into the Company’s and Independent Bank’s operations successfully and to reduce the combined costs of conducting the integration operations of the two banks, the anticipated cost savings may not be fully realized, if at all, or may take longer to realize than expected. The Company’s failure to realize those cost savings could materially adversely affect the Company’s financial condition, results of operations, capital, liquidity or cash flows. 17 The completion of the Company’s merger with Integrity would result in the immediate dilution of the Company’s existing shareholders’ ownership percentages in the Company’s common stock and their voting power, which could adversely affect the market for the Company’s common stock. The merger of Integrity with and into the Company would result in the issuance of a substantial number of additional shares of the Company’s common stock. That issuance would result in the immediate dilution of the percentage ownership and voting power of the existing holders of the Company’s common stock. Although the Company believes that the merger will be accretive to all of the Company’s shareholders, factors associated with the consummation of the merger of Integrity with and into the Company, such as those discussed above, could adversely affect the market for the Company’s common stock. If the goodwill that the Company recorded in connection with a business acquisition becomes impaired, it could require charges to earnings, which would have a negative impact on the Company’s financial condition and results of operations. Goodwill represents the amount by which the cost of an acquisition exceeded the fair value of net assets that the Company acquired in connection with the purchase of another financial institution. The Company reviews goodwill for impairment at least annually, or more frequently if events or changes in circumstances indicate that the carrying value of the asset might be impaired. The Company determines impairment by comparing the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. Any such adjustments are reflected in the Company’s results of operations in the periods in which they become known. As of December 31, 2017, the Company’s goodwill totaled $621.5 million. While the Company has not recorded any such impairment charges since the Company initially recorded the goodwill, there can be no assurance that the Company’s future evaluations of goodwill will not result in findings of impairment and related write-downs, which may have a material adverse effect on the Company’s financial condition and results of operations. Changes in interest rates may reduce net interest income and otherwise negatively impact the Company’s financial condition and results of operations. The majority of the Company’s banking assets are monetary in nature and subject to risk from changes in interest rates. Like most financial institutions, the Company’s earnings are significantly dependent on the Company’s net interest income, the principal component of the Company’s earnings, which is the difference between interest earned by the Company from the Company’s interest-earning assets, such as loans and investment securities, and interest paid by the Company on the Company’s interest-bearing liabilities, such as deposits and borrowings. The Company expects that it will periodically experience “gaps” in the interest rate sensitivities of the Company’s assets and liabilities, meaning that either its interest- bearing liabilities will be more sensitive to changes in market interest rates than the Company’s interest-earning assets, or vice versa. In either event, if market interest rates should move contrary to the Company’s position, this “gap” will negatively impact the Company’s earnings. The impact on earnings is more adverse when the slope of the yield curve flattens, that is, when short-term interest rates increase more than long-term interest rates or when long-term interest rates decrease more than short-term interest rates. Many factors impact interest rates, including governmental monetary policies, inflation, recession, changes in unemployment, the money supply, and international disorder and instability in domestic and foreign financial markets. Interest rate increases often result in larger payment requirements for the Company’s borrowers, which increase the potential for default. At the same time, the marketability of the property securing a loan may be adversely affected by any reduced demand resulting from higher interest rates. In a declining interest rate environment, there may be an increase in prepayments on loans as borrowers refinance their loans at lower rates. Changes in interest rates also can affect the value of loans, securities and other assets. An increase in interest rates that adversely affects the ability of borrowers to pay the principal or interest on loans may lead to an increase in nonperforming assets and a reduction of income recognized, which could have a material adverse effect on the Company’s results of operations and cash flows. Further, when the Company places a loan on nonaccrual status, the Company reverses any accrued but unpaid interest receivable, which decreases interest income. At the same time, the Company continues to have a cost to fund the loan, which is reflected as interest expense, without any interest income to offset the associated funding expense. Thus, an increase in the amount of nonperforming assets would have an adverse impact on net interest income. 18 If short-term interest rates remain at their historically low levels for a prolonged period, and assuming longer term interest rates fall further, the Company could experience net interest margin compression as the Company’s interest earning assets would continue to reprice downward while the Company’s interest-bearing liability rates could fail to decline in tandem. Such an occurrence would have a material adverse effect on the Company’s net interest income and the Company’s results of operations. The current interest rate environment has had, and may continue to have, an adverse effect upon the Company’s net interest income. Interest rates, which remain largely at historically low levels, are highly sensitive to many factors that are beyond our control such as general economic conditions and policies of the federal government, in particular the Federal Open Market Committee. In an attempt to help the overall economy, the FRB has kept interest rates low through its targeted Fed Funds rate. In December 2017, the FRB increased the Fed Funds rate by 75 basis points and indicates further increases during 2018, subject to economic conditions. As the FRB increases the Fed Funds rate, overall interest rates will likely rise, which may negatively impact the U.S. economic recovery. Further, changes in monetary policy, including changes in interest rates, could influence (i) the amount of interest the Company receives on loans and securities, (ii) the amount of interest the Company pays on deposits and borrowings, (iii) the Company's ability to originate loans and obtain deposits, (iv) the fair value of the Company's assets and liabilities, and (v) the reinvestment risk associated with a reduced duration of the Company's mortgage-backed securities portfolio as borrowers refinance to reduce borrowing costs. When interest-bearing liabilities reprice or mature more quickly than interest-earning assets, an increase in interest rates generally would tend to result in a decrease in net interest income. Although management believes it has implemented an effective asset and liability management strategy to manage the potential effects of changes in interest rates, including the use of adjustable rate and/or short-term assets, and FHLB advances, any substantial, unexpected, prolonged change in market interest rates could have a material adverse effect on the Company's financial condition and results of the Company's operation and/or the Company's strategies may not always be successful in managing the risk associated with changes in interest rates. The Company’s accounting estimates and risk management processes rely on analytical and forecasting models. The processes the Company uses to estimate its probable credit losses and to measure the fair value of financial instruments, as well as the processes used to estimate the effects of changing interest rates and other market measures on the Company’s financial condition and results of operations, depend upon the use of analytical and forecasting models. These models reflect assumptions that may not be accurate, particularly in times of market stress or other unforeseen circumstances. Even if these assumptions are accurate, the models may prove to be inadequate or inaccurate because of other flaws in their design or their implementation. If the models the Company uses for interest rate risk and asset-liability management are inadequate, the Company may incur increased or unexpected losses upon changes in market interest rates or other market measures. If the models the Company uses for determining its probable credit losses are inadequate, the allowance for credit losses may not be sufficient to support future charge-offs. If the models the Company uses to measure the fair value of financial instruments is inadequate, the fair value of such financial instruments may fluctuate unexpectedly or may not accurately reflect what the Company could realize upon sale or settlement of such financial instruments. Any such failure in the Company’s analytical or forecasting models could have a material adverse effect on the Company’s business, financial condition and results of operations. The Company could recognize losses on securities held in the Company’s securities portfolio, particularly if interest rates increase or economic and market conditions deteriorate. While the Company attempts to invest a significant percentage of its assets in loans (the Company’s loan to deposit ratio was 97.6% as of December 31, 2017), the Company invests a percentage of its total assets (approximately 8.8% as of December 31, 2017) in investment securities as part of its overall liquidity strategy. As of December 31, 2017, the fair value of the Company’s securities portfolio was approximately $763.0 million. 19 Factors beyond the Company’s control can significantly influence the fair value of securities in its portfolio and can cause potential adverse changes to the fair value of these securities. For example, fixed-rate securities are generally subject to decreases in market value when market interest rates rise. Additional factors include, but are not limited to, rating agency downgrades of the securities, defaults by the issuer or individual borrowers with respect to the underlying securities, and continued instability in the credit markets. Any of the foregoing factors could cause an other-than-temporary impairment in future periods and result in realized losses. The process for determining whether impairment is other-than-temporary usually requires difficult, subjective judgments about the future financial performance of the issuer and any collateral underlying the security in order to assess the probability of receiving all contractual principal and interest payments on the security. Because of changing economic and market conditions affecting market interest rates, the financial condition of issuers of the securities and the performance of the underlying collateral, the Company may recognize realized and/or unrealized losses in future periods, which could have an adverse effect on the Company’s financial condition and results of operations. A lack of liquidity could adversely affect the Company’s operations and jeopardize the Company’s business, financial condition and results of operations. Liquidity is essential to the Company’s business. The Company relies on its ability to generate deposits and effectively manage the repayment and maturity schedules of the Company’s loans and investment securities, respectively, to ensure that the Company has adequate liquidity to fund the Company’s operations. An inability to raise funds through deposits, borrowings, the sale of the Company’s investment securities, Federal Home Loan Bank advances, the sale of loans, and other sources could have a substantial negative effect on the Company’s liquidity. The Company’s most important source of funds consists of deposits. Deposit balances can decrease when customers perceive alternative investments as providing a better risk/return tradeoff. If customers move money out of bank deposits and into other investments, the Company would lose a relatively low- cost source of funds, increasing the Company’s funding costs and reducing the Company’s net interest income and net income. Other primary sources of funds consist of cash flows from operations, investment maturities and sales of investment securities, and proceeds from the issuance and sale of the Company’s equity and debt securities to investors. Additional liquidity is provided by the ability to borrow from the Federal Reserve Bank and the Federal Home Loan Bank. The Company also may borrow funds from third-party lenders, such as other financial institutions. The Company’s access to funding sources in amounts adequate to finance or capitalize the Company’s activities, or on terms that are acceptable to the Company, could be impaired by factors that affect the Company directly or the financial services industry or economy in general, such as disruptions in the financial markets or negative views and expectations about the prospects for the financial services industry. Any decline in available funding could adversely impact the Company’s ability to originate loans, invest in securities, meet the Company’s expenses, pay dividends to the Company’s shareholders, or to fulfill obligations such as repaying the Company’s borrowings or meeting deposit withdrawal demands, any of which could have a material adverse impact on the Company’s liquidity, business, financial condition and results of operations. The Company may need to raise additional capital in the future, and if the Company fails to maintain sufficient capital, whether due to losses, an inability to raise additional capital, growth or otherwise, the Company’s financial condition, liquidity and results of operations, as well as the Company’s ability to maintain regulatory compliance, would be adversely affected. The Company faces significant capital and other regulatory requirements as a financial institution. The Company may need to raise additional capital in the future to provide the Company with sufficient capital resources and liquidity to meet the Company’s commitments and business needs, which could include the possibility of financing acquisitions. In addition, the Company, on a consolidated basis, and Independent Bank, on a stand-alone basis, must meet certain regulatory capital requirements and maintain sufficient liquidity. The Company faces significant capital and other regulatory requirements as a financial institution. The Company’s ability to raise additional capital depends on conditions in the capital markets, economic conditions and a number of other factors, including investor perceptions regarding the banking industry, market conditions and governmental activities, and on the Company’s financial condition and performance. In the future, the Company may not be able to raise additional capital if needed or on terms acceptable to the Company. If the Company fails to maintain capital to meet regulatory requirements, the Company’s financial condition, liquidity and results of operations would be materially and adversely affected. The Company faces strong competition from financial services companies and other companies that offer banking services, which could harm the Company’s business. The Company conducts its operations almost exclusively in Texas and Colorado. Many of the Company’s competitors offer the same, or a wider variety of, banking services within the Company’s market areas. These competitors include banks with 20 nationwide operations, regional banks and other community banks. The Company also faces competition from many other types of financial institutions, including savings and loan institutions, finance companies, brokerage firms, insurance companies, credit unions, mortgage banks and other financial intermediaries. In addition, a number of out-of-state financial intermediaries have opened production offices, or otherwise solicit deposits, in the Company’s market areas. Increased competition in the Company’s markets may result in reduced loans and deposits, as well as reduced net interest margin and profitability. Ultimately, the Company may not be able to compete successfully against current and future competitors. If the Company is unable to attract and retain banking customers, the Company may be unable to continue to grow its loan and deposit portfolios, and the Company’s business, financial condition and results of operations may be adversely affected. The Company has a continuing need for technological change, and the Company may not have the resources to effectively implement new technology, or the Company may experience operational challenges when implementing new technology. The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. In addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. The Company’s future success will depend in part upon the Company’s ability to address the needs of the Company’s customers by using technology to provide products and services that will satisfy customer demands for convenience as well as to create additional efficiencies in the Company’s operations as it continues to grow and expand the Company’s market area. The Company may experience operational challenges as it implements these new technology enhancements or products, which could result in the Company not fully realizing the anticipated benefits from such new technology or require the Company to incur significant costs to remedy any such challenges in a timely manner. Many of the Company’s larger competitors have substantially greater resources to invest in technological improvements. In addition, the rise of “FinTech” entities presents an additional group of competitors which provide financial services through new electronic delivery systems. As a result, these competitors may be able to offer additional or superior products to those that the Company will be able to provide, which would put the Company at a competitive disadvantage. Accordingly, the Company may not be able to effectively implement new technology-driven products and services or be successful in marketing such products and services to its customers. System failure or cybersecurity breaches of the Company’s network security could subject the Company to increased operating costs as well as litigation and other liabilities. The computer systems and network infrastructure the Company uses could be vulnerable to unforeseen problems. The Company’s operations are dependent upon its ability to protect its computer equipment against damage from physical theft, fire, power loss, telecommunications failure or a similar catastrophic event, as well as from cybersecurity breaches, denial of service attacks, viruses, worms and other disruptive problems caused by hackers. Any damage or failure that causes breakdowns or disruptions in the Company’s customer relationship management, general ledger, deposit, loan and other systems could damage the Company’s reputation, result in a loss of customer business, subject the Company to additional regulatory scrutiny, or expose the Company to civil litigation and possible financial liability, any of which could have a material adverse effect on the Company. Computer break-ins, phishing and other cybersecurity disruptions could also jeopardize the security of information stored in and transmitted through the Company’s computer systems and network infrastructure, which may result in significant liability to the Company and may cause existing and potential customers to refrain from doing business with the Company. In addition, advances in computer capabilities could result in a compromise or breach of the systems the Company and the Company’s third-party service providers use to encrypt and protect customer transaction data. A failure of such security measures could have a material adverse effect on the Company’s financial condition and results of operations. The Company may be materially and adversely affected by the creditworthiness and liquidity of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. The Company has exposure to many different industries and counterparties, and routinely executes transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, and other institutional customers. Many of these transactions expose the Company to credit risk in the event of a default by a counterparty or customer. In addition, the Company’s credit risk may be exacerbated when the collateral held by the Company cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure due to the Company. Any such losses could have a material adverse effect on the Company. 21 The Company’s operations could be interrupted if the Company’s third-party service providers experience difficulty, terminate their services or fail to comply with banking regulations. The Company depends on a number of relationships with third-party service providers. Specifically, the Company receives core systems processing, essential web hosting and other Internet systems, deposit processing and other processing services from third-party service providers. If these third-party service providers experience difficulties, or terminate their services, and the Company is unable to replace them with other service providers, particularly on a timely basis, the Company’s operations could be interrupted. If an interruption were to continue for a significant period of time, the Company’s business, financial condition and results of operations could be adversely affected, perhaps materially. Even if the Company is able to replace third party service providers, it may be at a higher cost to the Company, which could adversely affect the Company’s business, financial condition and results of operations. The Company is subject to certain operational risks, including, but not limited to, customer or employee fraud and data processing system failures and errors. Employee errors and employee and customer misconduct could subject the Company to financial losses or regulatory sanctions and seriously harm the Company’s reputation. Misconduct by the Company’s employees could include hiding unauthorized activities from the Company, improper or unauthorized activities on behalf of the Company’s customers or improper use of confidential information. Customers are also subject to financial crimes, including fraud, wire fraud, and cyber-crimes, which could adversely impact their ability to pay loans or result in a fraudulent removal of funds from their deposit accounts. It is not always possible to prevent employee errors and misconduct, or fraudulent schemes impacting customers, and the precautions the Company takes to prevent and detect this activity may not be effective in all cases. Employee errors could also subject the Company to financial claims for negligence. The Company maintains a system of internal controls and insurance coverage to mitigate against operational risks, including data processing system failures and errors and customer or employee fraud. If the Company’s internal controls fail to prevent or detect an occurrence, or if any resulting loss is not insured or exceeds applicable insurance limits, it could have a material adverse effect on the Company’s business, financial condition and results of operations. In addition, the Company relies heavily upon information supplied by third parties, including the information contained in credit applications, property appraisals, title information, equipment pricing and valuation and employment and income documentation, in deciding which loans the Company will originate, as well as the terms of those loans. If any of the information upon which the Company relies is misrepresented, either fraudulently or inadvertently, and the misrepresentation is not detected prior to asset funding, the value of the asset may be significantly lower than expected, or the Company may fund a loan that the Company would not have funded or on terms the Company would not have extended. Whether a misrepresentation is made by the applicant or another third party, the Company generally bears the risk of loss associated with the misrepresentation. A loan subject to a material misrepresentation is typically unsellable or subject to repurchase if it is sold prior to detection of the misrepresentation. The sources of the misrepresentations are often difficult to locate, and it is often difficult to recover any of the monetary losses that the Company may suffer. Natural disasters, severe weather events, worldwide hostilities, including terrorist attacks, and other external events may adversely affect the general economy, the financial services industry, the industries of customers, and the Company. Natural disasters, severe weather events, including those prominent in Texas and Colorado and those prominent in the geographic areas of vendors and business partners, together with worldwide hostilities, including terrorist attacks, and other external events could have a significant impact on the Company’s ability to conduct business. These events could also affect the stability of the Company’s deposit base, borrowers’ ability to repay loans, impair collateral, result in a loss of revenue or an increase in expenses. Although the Company has established disaster recovery and business continuity procedures and plans, the occurrence of any such event may adversely affect the Company’s business, which in turn could have a material adverse effect on the Company’s financial condition and results of operations. Hurricanes, tornadoes, wildfires, earthquakes and other natural disasters and severe weather events have caused, and in the future may cause, widespread property damage and significantly and negatively affect the local economies in which the Company operates. For example, in late August 2017, Hurricane Harvey, a Category 4 hurricane, caused catastrophic flooding and unprecedented damage to residences and businesses across Southeast Texas, including Houston. The Company currently operates 10 banking centers in the greater Houston area. The effect of Hurricane Harvey, and other catastrophic weather events if they were to occur, could have a materially adverse impact on the Company’s financial condition, results of operations and business, as well as potentially increase the Company’s exposure to credit losses and liquidity risks. 22 New lines of business or new products and services may subject the Company to additional risks. From time to time, the Company may implement or may acquire new lines of business or offer new products and services within existing lines of business. There are substantial risks and uncertainties associated with these efforts, particularly in instances where the markets are not fully developed. In developing and marketing new lines of business and/or new products and services, the Company may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives and shifting market preferences, may also impact the successful implementation of a new line of business or a new product or service. Furthermore, any new line of business and/or new product or service could have a significant impact on the effectiveness of the Company’s system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business or new products or services could have a material adverse effect on the Company’s business, financial condition and results of operations. Legal and regulatory proceedings could adversely affect the Company’s business, financial condition, and results of operation. The Company, like all financial institutions, has been and may in the future become involved in legal and regulatory proceedings. The Company considers most of these proceedings to be in the normal course of business or typical for the industry. However, it is inherently difficult to assess the outcome of these matters. Any material legal or regulatory proceeding could impose substantial cost and cause management to divert its attention from the Company’s business and operations. Any adverse determination in a legal or regulatory proceeding could have a material adverse effect on the Company’s business, financial condition and results of operations. The Company is subject to claims and litigation pertaining to intellectual property from time to time. Banking and other financial services companies, such as the Company, rely on technology companies to provide information technology products and services necessary to support the Company’s day-to-day operations. Technology companies frequently enter into litigation based on allegations of patent infringement or other violations of intellectual property rights. In addition, patent holding companies seek to monetize patents they have purchased or otherwise obtained. Competitors of the Company’s vendors, or other individuals or companies, have from time to time claimed to hold intellectual property sold to the Company by its vendors. Such claims may increase in the future as the financial services sector becomes more reliant on information technology vendors. The plaintiffs in these actions frequently seek injunctions and substantial damages. Regardless of the scope or validity of such patents or other intellectual property rights, or the merits of any claims by potential or actual litigants, the Company may have to engage in protracted litigation. Such litigation is often expensive, time- consuming, disruptive to the Company’s operations and distracting to management. If the Company is found to infringe one or more patents or other intellectual property rights, it may be required to pay substantial damages or royalties to a third-party. In certain cases, the Company may consider entering into licensing agreements for disputed intellectual property, although no assurance can be given that such licenses can be obtained on acceptable terms or that litigation will not occur. These licenses may also significantly increase the Company’s operating expenses. If legal matters related to intellectual property claims were resolved against the Company or settled, the Company could be required to make payments in amounts that could have a material adverse effect on its business, financial condition and results of operations. The Company could experience claims and litigation pertaining to fiduciary responsibility. From time to time, customers make claims and take legal action pertaining to the Company’s performance of its fiduciary responsibilities. Whether customer claims and legal action related to the Company’s performance of its fiduciary responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to the Company, they may result in significant financial liability, adversely affect the market perception of the Company and its products and services and/or impact customer demand for those products and services. Any financial liability or reputation damage could have a material adverse effect on the Company’s business, financial condition and results of operations. 23 The Company could be subject to environmental risks and associated costs on the Company’s foreclosed real estate assets, which could materially and adversely affect the Company. A significant portion of the Company’s loan portfolio is secured by real property. During the ordinary course of business, the Company may foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, the Company may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require the Company to incur substantial expenses and may materially reduce the affected property’s value or limit the Company’s ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase the Company’s exposure to environmental liability. Although the Company has policies and procedures to perform an environmental review before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on the Company’s financial condition and results of operations. The Company’s Chairman and Chief Executive Officer, the Company’s largest shareholder, and certain other officers and directors of the Company, are business partners in business ventures in addition to the Company, which creates potential conflicts of interest and corporate governance issues. Messrs. David Brooks, Viola, Cifu, and Daniel Brooks are partners in Himalayan Ventures, LP, a real estate investment partnership. A dispute between these individuals in connection with this business venture outside of the Company could impact their relationship at the Company and, because of their prominence within the Company, the Company itself. Risks Related to an Investment in the Company’s Common Stock The Company’s stock can be volatile. Stock price volatility may make it more difficult for you to resell your common stock when you want and at prices you find attractive. The Company’s stock price can fluctuate significantly in response to a variety of factors including, among other things: • • • • • • • • • • actual or anticipated variations in quarterly results of operations; recommendations by securities analysts; operating and stock price performance of other companies that investors deem comparable to the Company; new reports relating to trends, concerns and other issues in the financial services industry; perceptions in the marketplace regarding the Company and/or its competitors; new technology used, or services offered, by competitors; significant acquisitions or business combinations involving the Company or its competitors; the public float and trading volumes for the Company’s common stock; changes in government regulations, including tax laws; and volatility in economic conditions, including changes in interest rates, disruption in energy markets and changes in the global economy. In addition, although the Company’s common stock is listed for trading on the Nasdaq Global Select Market, the trading volume of the Company’s common stock is less than that of other, larger financial institutions. Given the lower trading volume, significant sales of Company common stock, or the expectation of such sales, could cause the stock price to fall. The Company is dependent upon Independent Bank for cash flow, and Independent Bank’s ability to make cash distributions is restricted. The Company’s primary tangible asset is Independent Bank. As such, the Company depends upon Independent Bank for cash distributions (through dividends on Independent Bank’s stock) that the Company uses to pay the Company’s operating expenses, satisfy the Company’s obligations (including the Company’s senior indebtedness, subordinated debentures, and junior subordinated indebtedness issued in connection with trust preferred securities), and to pay dividends on the Company’s common stock and preferred stock. There are numerous laws and banking regulations that limit Independent Bank’s ability to pay dividends to the Company. If Independent Bank is unable to pay dividends to the Company, the Company will not be able to satisfy the Company’s obligations or pay dividends on the Company’s common stock and preferred stock. Federal and state statutes and regulations restrict Independent Bank’s ability to make cash distributions to the Company. These statutes and regulations require, among other things, that Independent Bank maintain certain levels of capital in order to pay a dividend. Further, state and federal banking authorities have the ability to restrict the payment of dividends by supervisory action. 24 The Company’s dividend policy may change without notice, and the Company’s future ability to pay dividends is subject to restrictions. The Company may change its dividend policy at any time without notice to the Company’s shareholders. Holders of the Company’s common stock are entitled to receive only such dividends as the Company’s board of directors may declare out of funds legally available for such payments. Any declaration and payment of dividends on preferred stock and common stock will depend upon the Company’s earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, the Company’s ability to service any equity or debt obligations senior to the preferred stock and, ultimately, the common stock and other factors deemed relevant by its board of directors. Furthermore, consistent with the Company’s strategic plans, growth initiatives, capital availability, projected liquidity needs, and other factors, the Company has made, and will continue to make, capital management decisions and policies that could adversely impact the amount of dividends, if any, paid to the Company’s common shareholders. The Federal Reserve has indicated that bank holding companies should carefully review their dividend policy in relation to the organization’s overall asset quality, level of current and prospective earnings and level, composition and quality of capital. The guidance provides that the Company inform and consult with the Federal Reserve prior to declaring and paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in an adverse change to the Company’s capital structure, including interest on senior debt, subordinated debt and the subordinated debentures underlying the Company’s trust preferred securities. If required payments on the Company’s outstanding senior debt, subordinated debt and junior subordinated debentures, held by its unconsolidated subsidiary trusts, are not made or are suspended, the Company would be prohibited from paying dividends on its common stock. The Company’s largest shareholder and board of directors have historically controlled, and in the future may continue to be able to control, the Company. Collectively, as of February 26, 2018, Messrs. Vincent Viola and David Brooks owned 18.8% of the Company’s outstanding common stock on a fully diluted basis. Vincent Viola, the largest shareholder of the Company, currently owns 15.6% of the Company’s outstanding common stock, and David Brooks, the Company’s Chairman of the Board and Chief Executive Officer, currently owns 3.2% of the Company’s common stock, each calculated on a fully diluted basis. Further, as of the date hereof, the Company’s other directors and executive officers currently own collectively approximately 15% of the Company’s outstanding common stock. As a result, these individuals exert controlling influence in the Company’s management and policies. Further, given the large ownership position of these individuals, it will be difficult for any other shareholder to elect members to the Company’s board of directors or otherwise influence the Company’s management or direction. In addition, two of the Company’s directors have close professional and personal ties to Vincent Viola, the Company’s largest shareholder. Doug Cifu is the Chief Executive Officer of Virtu Financial, LLC, Mr. Viola’s primary operating entity; and Michael Viola is the son of Vincent Viola. Further, David Brooks, the Company’s Chairman and Chief Executive Officer, has a 30 year history of ownership and operation of Independent Bank with Vincent Viola; and he has joint investments with Mr. Viola outside of the Company. Given these close relationships, even though he does not serve on the Company’s board, Mr. Viola has and will continue to have a large influence over the direction and operation of the Company. The Company’s corporate organizational documents and the provisions of Texas law to which the Company is subject contain certain provisions that could have an anti-takeover effect and may delay, make more difficult or prevent an attempted acquisition of the Company that you may favor. The Company’s certificate of formation and bylaws contain various provisions that could have an anti-takeover effect and may delay, discourage or prevent an attempted acquisition or change in control of the Company. These provisions include the following: • • • • • staggered terms for directors; a provision that directors cannot be removed except for cause; a provision that any special meeting of the Company’s shareholders may be called only by a majority of the Company’s board of directors, the Chairman or a holder or group of holders of at least 20% of the Company’s shares entitled to vote at such special meeting; a provision that requires the vote of two-thirds of the shares outstanding for major corporate actions, such as an amendment to the Company’s certificate of formation or bylaws or the approval of a merger; and a provision establishing certain advance notice procedures for nomination of candidates for election as directors and for shareholder proposals to be considered only at an annual or special meeting of shareholders. 25 The Company’s certificate of formation provides for noncumulative voting for directors and authorizes the board of directors to issue shares of its preferred stock without shareholder approval and upon such terms as the board of directors may determine. The issuance of the Company’s preferred stock, while providing desirable flexibility in connection with possible acquisitions, financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a controlling interest in the Company. In addition, certain provisions of Texas law, including a provision which restricts certain business combinations between a Texas corporation and certain affiliated shareholders, may delay, discourage or prevent an attempted acquisition or change in control of the Company. Also, the Company’s certificate of formation prohibits shareholder action by written consent. The holders of the Company’s debt obligations and any shares of the Company’s preferred stock that may be outstanding in the future will have priority over the Company’s common stock with respect to payment in the event of liquidation, dissolution or winding up and with respect to the payment of interest and preferred dividends. In the event of any winding up and termination of the Company, the Company common stock would rank below all claims of the holders of the Company’s debt and any preferred stock then outstanding. The Company has a senior, revolving credit facility under which the Company may borrow up to $50 million. As of December 31, 2017, the Company currently had not drawn upon this credit facility. Further, as of December 31, 2017, the Company had outstanding • • $140.0 million of aggregate principal amount of subordinated indebtedness; and $31.6 million of subordinated debentures issued in connection with trust preferred securities Upon the winding up and termination of the Company, holders of the Company’s common stock will not be entitled to receive any payment or other distribution of assets until after all of the Company’s obligations to the Company’s debt holders have been satisfied and holders of the Company’s senior debt, subordinated debt, and junior subordinated debentures issued in connection with trust preferred securities have received any payments and other distributions due to them. In addition, the Company is required to pay interest on the Company’s senior debt, subordinated debt and subordinated debentures and junior subordinated debentures issued in connection with the Company’s trust preferred securities before the Company pays any dividends on the Company’s common stock. Furthermore, the Company’s board of directors may also, in its sole discretion, designate and issue one or more series of preferred stock from the Company’s authorized and unissued preferred stock, which may have preferences with respect to common stock in dissolution, dividends, liquidation or otherwise. An investment in the Company’s common stock is not an insured deposit and is not guaranteed by the FDIC, so you could lose some or all of your investment. An investment in the Company’s common stock is not a bank deposit and, therefore, is not insured against loss or guaranteed by the FDIC, any other deposit insurance fund or by any other public or private entity. An investment in the Company’s common stock is inherently risky for the reasons described in this report and shareholders who acquire the Company’s common stock could lose some or all of their investment. Risks Related to the Business Environment and the Company’s Industry The Company operates in a highly regulated environment and, as a result, is subject to extensive regulation and supervision. The Company and Independent Bank are subject to extensive federal and state regulation and supervision. Banking regulations are primarily intended to protect depositors’ funds, federal deposit insurance funds and the banking system as a whole, not the Company’s shareholders. These regulations affect the Company’s lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. Any change in applicable regulations or federal or state legislation could have a substantial impact on the Company, Independent Bank and their respective operations. The Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial institutions regulatory regimes in light of the recent performance of and government intervention in the financial services sector. Additional legislation and regulations or regulatory policies, including changes in interpretation or implementation of statutes, regulations or policies, could significantly affect the Company’s powers, authority and operations, or the powers, authority and operations of Independent Bank in substantial and unpredictable ways. Further, regulators have significant discretion and power to prevent or remedy unsafe or unsound practices or violations of laws by banks and bank holding companies in the performance of their supervisory and enforcement duties. The exercise of this regulatory discretion and power could have a negative impact on the 26 Company. Failure to comply with laws, regulations or policies could result in sanctions by regulatory agencies, civil money penalties and/or reputation damage, which could have a material adverse effect on the Company’s business, financial condition and results of operations. The Dodd-Frank Act created the Consumer Financial Protection Bureau, or the CFPB, with broad powers to supervise and enforce consumer protection laws. The CFPB has broad rule-making authority, including the authority to prohibit unfair, deceptive, and abusive acts and practices. Compliance with the CFPB rules required changes to the Company’s underwriting practices with respect to mortgage loans, and has resulted in increased regulatory compliance costs. These rules may subject the Company to increased potential liabilities related to residential mortgage lending activities. With the Company approaching $10 billion in consolidated assets following the Carlile acquisition, management is beginning to prepare for satisfying the stress testing requirements contained in the Dodd-Frank Act (“DFAST”). DFAST stress testing is designed to evaluate the Company’s capital and liquidity planning. The Company expects to incur significant expense in analyzing its current capital planning systems, implementing new data gathering systems and expanding its regulatory compliance and financial staff to satisfy the DFAST stress testing requirements. These costs and expenses will adversely impact the Company’s earnings. Further, uncertainties regarding how the financial models created pursuant to this requirement will respond to the regulatory scenarios issued annually, and how the regulators will evaluate the Company’s report of the results obtained through the stress testing process, subject the Company to risk when and if the Company becomes subject to DFAST and as the standards for DFAST evolve. Any change to the Company’s DFAST stress testing practices or any additional capital required by regulators in connection with the DFAST requirements may have a material adverse effect on the Company’s financial condition and results of operations. Monetary policies and regulations of the Federal Reserve could adversely affect the Company’s business, financial condition and results of operations. In addition to being affected by general economic conditions, the Company’s earnings and growth are affected by the policies of the Federal Reserve. An important function of the Federal Reserve is to regulate the money supply and credit conditions. Among the instruments used by the Federal Reserve to implement these objectives are open market operations in U.S. government securities, adjustments of the discount rate and changes in reserve requirements against bank deposits. These instruments are used in varying combinations to influence overall economic growth and the distribution of credit, bank loans, investments and deposits. Their use also affects interest rates charged on loans or paid on deposits. The monetary policies and regulations of the Federal Reserve have had a significant effect on the operating results of commercial banks in the past and are expected to continue to do so in the future. The Company cannot predict the effects of such policies upon the Company’s business, financial condition and results of operations. The Federal Reserve may require the Company to commit capital resources to support Independent Bank. The Federal Reserve, which examines the Company and Independent Bank, requires a bank holding company to act as a source of financial and managerial strength to a subsidiary bank and to commit resources to support such subsidiary bank. Under the “source of strength” doctrine, the Federal Reserve may require a bank holding company to make capital injections into a troubled subsidiary bank and may charge the bank holding company with engaging in unsafe and unsound practices for failure to commit resources to such a subsidiary bank. In addition, the Dodd-Frank Act directs the federal bank regulators to require that all companies that directly or indirectly control an insured depository institution serve as a source of strength for the institution. Under these requirements, in the future, the Company could be required to provide financial assistance to Independent Bank if it experiences financial distress. A capital injection may be required at times when the Company does not have the resources to provide it, and therefore the Company may be required to borrow the funds. In the event of a bank holding company’s bankruptcy, the bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the holding company’s general unsecured creditors, including the holders of its note obligations. Thus, any borrowing that must be done by the holding company in order to make the required capital injection becomes more difficult and expensive and will adversely impact the holding company’s cash flows, financial condition, results of operations and prospects. 27 Federal banking agencies periodically conduct examinations of the Company’s business, including compliance with laws and regulations, and the Company’s failure to comply with any supervisory actions to which the Company becomes subject as a result of such examinations could materially and adversely affect the Company. Texas and federal banking agencies periodically conduct examinations of the Company’s business, including compliance with laws and regulations. If, as a result of an examination, a Texas or federal banking agency were to determine that the financial condition, capital resources, asset quality, earnings prospects, management, liquidity or other aspects of the Company’s operations had become unsatisfactory, or that the Company or its management was in violation of any law or regulation, it may take a number of different remedial actions as it deems appropriate. These actions include the power to enjoin “unsafe or unsound” practices, to require affirmative actions to correct any conditions resulting from any violation or practice, to issue an administrative order that can be judicially enforced, to direct an increase in the Company’s capital, to restrict the Company’s growth, to assess civil monetary penalties against Independent Bank, the Company’s officers or directors, to remove officers and directors and, if it is concluded that such conditions cannot be corrected or there is an imminent risk of loss to depositors, to terminate the Company’s deposit insurance. If the Company becomes subject to such regulatory actions, the Company could be materially and adversely affected. The Company may be required to pay significantly higher FDIC deposit insurance assessments in the future, which could materially and adversely affect the Company. Previous economic conditions and the Dodd-Frank Act caused the FDIC to increase deposit insurance assessments and may result in increased assessments in the future. On February 7, 2011, the FDIC approved a final rule that amended the Deposit Insurance Fund restoration plan and implemented certain provisions of the Dodd-Frank Act. Effective April 1, 2011, the assessment base is determined using average consolidated total assets minus average tangible equity rather than the previous assessment base of adjusted domestic deposits. The final rule also provides the FDIC’s board with the flexibility to adopt actual rates that are higher or lower than the total base assessment rates adopted on February 7, 2011 without notice and comment, if certain conditions are met. An increase in the assessment rates could materially and adversely affect the Company. The Company faces a risk of noncompliance and enforcement action with the Bank Secrecy Act and other anti-money laundering statutes and regulations. The federal Bank Secrecy Act, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, or Patriot Act, and other laws and regulations require financial institutions, among other duties, to institute and maintain effective anti-money laundering programs and file suspicious activity and currency transaction reports as appropriate. The federal Financial Crimes Enforcement Network, established by the Treasury to administer the Bank Secrecy Act, is authorized to impose significant civil money penalties for violations of those requirements and has recently engaged in coordinated enforcement efforts with the individual federal banking regulators, as well as the U.S. Department of Justice, Drug Enforcement Administration and Internal Revenue Service. There is also increased scrutiny of compliance with the rules enforced by the Office of Foreign Assets Control. If the Company’s policies, procedures and systems are deemed deficient or the policies, procedures and systems of the financial institutions that the Company has already acquired or may acquire in the future are deficient, the Company would be subject to liability, including fines and regulatory actions such as restrictions on the Company’s ability to pay dividends and the necessity to obtain regulatory approvals to proceed with certain aspects of the Company’s business plan (including the Company’s acquisition plans), which would negatively impact the Company’s business, financial condition and results of operations. Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have serious reputational consequences for the Company. There are substantial regulatory limitations on changes of control of bank holding companies. With certain limited exceptions, federal regulations prohibit a person or company or a group of persons deemed to be “acting in concert” from, directly or indirectly, acquiring more than 10% (5% if the acquirer is a bank holding company) of any class of the Company’s voting stock or obtaining the ability to control in any manner the election of a majority of the Company’s directors or otherwise direct the management or policies of the Company without prior notice or application to and the approval of the Federal Reserve. Accordingly, prospective investors need to be aware of and comply with these requirements, if applicable, in connection with any such purchase of shares of the Company’s common stock. These provisions effectively inhibit certain mergers or other business combinations, which, in turn, could adversely affect the market price of the Company’s common stock 28 ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES The Company owns its corporate headquarters, which is a 62,000 square foot, four story office building located at 1600 Redbud Blvd., Suite 400, McKinney, Texas 75069, and serves as Independent Bank’s home office. The Company’s building is the most prominent office building in McKinney, providing significant visibility and enhancing the Company’s brand in Collin County. The Company’s remodeling of its headquarters building won U.S. Green Building Council’s “2010 LEED Silver Certification.” At December 31, 2017, in addition to our corporate office, we had 70 full-service branches. The Company believes that its facilities are in good condition and are adequate to meet the Company’s operating needs for the foreseeable future. At December 31. 2017, we owned 56 of our branches, and leased the remaining facilities. The majority of our branches are located in the North Texas area, including McKinney, Dallas, Fort Worth, Denton and Sherman/Denison, the Austin/Central Texas area, including Austin and Waco, the Houston Texas metropolitan area and along the Colorado Front Range area, including Denver and Colorado Springs. On January 17, 2018, the Company broke ground on a new corporate headquarters located on a 10.4 acre parcel of land at State Highway 121 and Grand Ranch Parkway at the entrance to the McKinney Corporate Center Craig Ranch in McKinney, Texas. The approximately 165,000 square-foot, six story facility will allow space for the Company’s continued growth. The building is expected to be completed in the first quarter of 2019, although delays could occur. For more information about our premises and equipment and our lease commitments, see Note 7 and Note 14, respectively, of the Notes to Consolidated Financial Statements in Item 15 of this report. ITEM 3. LEGAL PROCEEDINGS In the normal course of business, the Company and Independent Bank are named as defendants in various lawsuits. Management of the Company and Independent Bank, following consultation with legal counsel, do not expect the ultimate disposition of any, or a combination, of these matters to have a material adverse effect on the business of the Company or Independent Bank. A legal proceeding that the Company believes could become material is described below. Independent Bank is a party to a legal proceeding inherited by Independent Bank in connection with the Company's acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston, or BOH, that was completed on April 15, 2014. Several entities related to R. A. Stanford, or the Stanford Entities, including Stanford International Bank, Ltd., or SIBL, had deposit accounts at BOH. Certain individuals who had purchased certificates of deposit from SIBL filed a class action lawsuit against several banks, including BOH, on November 11, 2009 in the U.S. District Court Northern District of Texas, Dallas Division, in a case styled Peggy Roif Rotstain, et al. on behalf of themselves and all others similarly situated, v. Trustmark National Bank, et al., Civil Action No. 3:09-CV-02384-N-BG. The suit alleges, among other things, that the plaintiffs were victims of fraud by SIBL and other Stanford Entities and seeks to recover damages and alleged fraudulent transfers by the defendant banks. On May 1, 2015, the plaintiffs filed a motion requesting permission to file a Second Amended Class Action Complaint in this case, which motion was subsequently granted. The Second Amended Class Action Complaint asserted previously unasserted claims, including aiding and abetting or participation in a fraudulent scheme based upon the large amount of deposits that the Stanford Entities held at BOH and the alleged knowledge of certain BOH officers. The plaintiffs seek recovery from Independent Bank and other defendants for their losses. The case was inactive due to a court-ordered discovery stay issued March 2, 2015 pending the Court’s ruling on plaintiff’s motion for class certification and designation of class representatives and counsel. On November 7, 2017, the Court issued an order denying the plaintiff’s motion. In addition, the Court lifted the previously ordered discovery stay. On January 11, 2018, the Court entered a scheduling order providing that the case be ready for trial on January 27, 2020. The Company anticipates an increase in legal fees associated with the defense of this claim as the case proceeds to trial. Independent Bank notified its insurance carriers of the claims made in the Second Amended Class Action Complaint. The insurance carriers have initially indicated that a “loss” has not yet occurred or that the claims are not covered by the policies. However, Independent Bank is continuing to pursue insurance coverage for these claims, as well as for the reimbursement of defense costs, through the initiation of litigation and other means. 29 Independent Bank believes that the claims made in this lawsuit are without merit and is vigorously defending this lawsuit. This is complex litigation involving a number of procedural matters and issues. As such, Independent Bank is unable to predict when this matter may be resolved and, given the uncertainty of litigation, the ultimate outcome of, or potential costs or damages arising from, this case.

MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Common Stock Market Prices Since January 2, 2014, the Company's common stock has traded on the Nasdaq Global Select Market under the symbol “IBTX.” Quotations of the sales volume and the closing sales prices of the common stock of the Company are listed daily in the Nasdaq Global Select Market’s listings. As of February 26, 2018, there were 407 holders of record for the Company's common stock. The following table sets forth, for the periods indicated, the high and low intraday sales prices for the Company common stock as reported by the Nasdaq Global Select Market: Quarter ending March 31, 2018 (through February 26, 2018) Quarter ended March 31, 2017 Quarter ended June 30, 2017 Quarter ended September 30, 2017 Quarter ended December 31, 2017 Quarter ended March 31, 2016 Quarter ended June 30, 2016 Quarter ended September 30, 2016 Quarter ended December 31, 2016 Dividends $ $ $ High 75.95 66.85 65.30 62.40 72.28 34.95 43.00 45.00 65.65 $ $ $ Low 65.50 58.35 54.55 51.70 59.25 25.74 25.50 34.00 43.00 Payment of Dividends on Common Stock. The following table summarizes the cash dividends paid on the Company's common stock for the interim period through February 26, 2018 and for the quarterly periods in the years ended December 31, 2017 and 2016. Quarter ending March 31, 2018 (through February 26, 2018) Quarter ended March 31, 2017 Quarter ended June 30, 2017 Quarter ended September 30, 2017 Quarter ended December 31, 2017 Quarter ended March 31, 2016 Quarter ended June 30, 2016 Quarter ended September 30, 2016 Quarter ended December 31, 2016 Cash Dividends Declared per Share $ $ $ 0.12 0.10 0.10 0.10 0.10 0.08 0.08 0.08 0.10 The Company currently expects to continue to pay (when, as and if declared by the Company’s board of directors out of funds legally available for that purpose and subject to regulatory restrictions) regular quarterly cash dividends on its common stock; however, there can be no assurance that the Company will continue to pay dividends in the future. Future dividends on the Company common stock will depend upon its earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, the Company's ability to service any equity or debt obligations senior to the common stock (including the Company’s senior debt and preferred stock discussed below) and other factors deemed relevant by the board of directors of the Company. 31 As a holding company, the Company is ultimately dependent upon its subsidiaries, particularly Independent Bank, to provide funding for its operating expenses, debt service and dividends. Various banking laws applicable to Independent Bank limit the payment of dividends and other distributions by Independent Bank to the Company, and may therefore limit the Company’s ability to pay dividends on its common stock. Regulatory authorities could impose administratively stricter limitations on the ability of Independent Bank to pay dividends to the Company if such limits were deemed appropriate to preserve certain capital adequacy requirements. Under the credit agreement between the Company and U.S. Bank National Association, or U.S. Bank, the Company cannot make any dividend payments without the prior written consent of U.S. Bank; provided, however, that, so long as no default under the credit agreement has occurred and is continuing, or will occur as a result of any such dividend, the Company may pay dividends to its shareholders as permitted by applicable governmental laws and regulations, including dividends with respect to the Company’s common stock. Under the terms of the Company’s junior subordinated debentures held by the Company’s unconsolidated subsidiary trusts, if required payments on such junior subordinated debentures are not made or suspended, the Company would be prohibited from paying dividends on its common stock. Recent Sales of Unregistered Securities On November 21, 2016, the Company entered into securities purchase agreements, or Stock Purchase Agreements, with a limited number of institutional investors who were all accredited investors pursuant to which the Company agreed to sell in a private placement an aggregate of 400,000 shares of the Company’s common stock, or the Private Placement Shares, at a purchase price of $52.50 per Private Placement Share. The gross proceeds of the sale of such Private Placement Shares was approximately $21 million, and the placement discount/commission to Stephens, Inc., as placement agent, was $1,050,000. The transaction closed on November 29, 2016. The Company used the proceeds of the offering to support the Carlile acquisition and for general corporate purposes. The Stock Purchase Agreements contained representations and warranties, covenants and indemnification provisions that are customary for private placements of shares of common stock by companies with shares of common stock listed for trading on a national securities exchange. The Private Placement Shares were not registered under the Securities Act of 1933, as amended, or the Securities Act, in reliance on the exemption from registration in Section 4(a)(2) of the Securities Act and Regulation D of the Commission promulgated under the Securities Act, and, as a result, the Private Placement Shares may not be offered or sold in the United States absent a registration statement or exemption from registration. As agreed in the Stock Purchase Agreements, the Company filed with the Commission a registration statement (File No. 333-215137) with respect to the resale of the Private Placement Shares purchased by the investors under the Stock Purchase Agreements and that registration statement was declared effective by the Commission on December 21, 2016.

SELECTED FINANCIAL DATA The following selected consolidated financial data of the Company for, and as of, the end of each of the years in the five-year period ended December 31, 2017, is derived from and should be read in conjunction with the Company’s consolidated financial statements and the notes thereto appearing elsewhere in this Annual Report on Form 10-K. You should read the following financial information relating to the Company in conjunction with other information contained in this Annual Report on Form 10-K, including the information set forth in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under Part II, Item 7, beginning on page 38 and the consolidated financial statements of the Company and related accompanying notes included elsewhere in this Annual Report on Form 10-K. The Company’s historical results for any prior period are not necessarily indicative of results to be expected in any future period. As described elsewhere in this Annual Report on Form 10-K, the Company has consummated several acquisitions in recent fiscal periods. The results and other financial information of those acquired operations are not included in the information below for the periods prior to their respective acquisition dates and, therefore, the results for these prior periods are not comparable in all respects and may not be predictive of the Company’s future results.

As of April 1, 2013, the Company terminated its S corporation election and commenced being subject to federal income taxation as a C corporation. The Company has calculated its pro forma net income, pro forma earnings per share on a basic and diluted basis, pro forma return on average assets and pro forma return on average equity for each period presented by calculating a pro forma provision for federal income taxes using an assumed annual effective federal income tax rate of 33.9% for the year ended December 31, 2013 and adjusting its historical net income for each period presented to give effect to the pro forma provision for federal income taxes for such period. The Company calculates its diluted earnings per share for each period shown as its net income divided by the weighted-average number of its common shares outstanding during the relevant period adjusted for the dilutive effect of its outstanding warrants to purchase shares of common stock. The increase in 2013 largely relates to the Company’s initial public offering, the increase in 2014 largely relates to shares issued in three acquisitions completed in 2014, the increase in 2015 relates to shares issued in the acquisition completed in November 2015, the increase in 2016 relates to the weighted effect of the shares issued in November 2015 along with shares issued in a private offering during 2016 and the increase in 2017 relates to shares issued in the acquisition completed in April 2017 along with shares issued in a public offering during 2017. See Note 1 to the Company’s consolidated financial statements appearing elsewhere in this Annual Report on Form 10 K for more information regarding the dilutive effect of its outstanding warrants and regarding certain nonvested shares of common stock, the effect of which is anti-dilutive. Earnings per share on a basic and diluted basis and pro forma earnings per share on a basic and diluted basis were calculated using the following outstanding share amounts, which includes participating shares (those shares with dividend rights): Weighted average shares outstanding-basic Weighted average shares outstanding-diluted For the Year Ended December 31, 2017 2016 2015 2014 2013 25,636,292 18,501,663 17,321,513 15,208,544 10,921,777 25,742,362 18,588,309 17,406,108 15,306,998 10,990,245 (3) (4) (5) (6) Dividends declared for the year ended December 31, 2013 include quarterly cash distributions paid to the Company’s shareholders as to the three months ended March 31, 2013 to provide them with funds to pay their federal income tax liabilities incurred as a result of the pass-through of the Company’s net taxable income for such periods to its shareholders as holders of shares in an S corporation for federal income tax purposes. The aggregate amounts of such cash distributions relating to the payment of tax liabilities were $0.52 per share for the year ended December 31, 2013. Book value per share equals the Company’s total common stockholders’ equity (excludes preferred stock) as of the date presented divided by the number of shares of its common stock outstanding as of the date presented. The number of shares of its common stock outstanding as of December 31, 2017, 2016, 2015, 2014 and 2013 was 28,254,893 shares, 18,870,312 shares, 18,399,194 shares, 17,032,669 shares, and 12,330,158 shares, respectively. Each of seven wholly owned, but nonconsolidated, subsidiaries of the Company holds a series of the Company’s junior subordinated debentures purchased by the subsidiary in connection with, and paid for with the proceeds of, the issuance of trust issued preferred securities by that subsidiary. The Company has guaranteed the payment of the amounts payable under each of those issues of trust preferred securities. During 2017 the Company assumed two trusts with the Carlile acquisition. The Company has calculated its return on average assets and return on average equity for a period by dividing net income for that period by its average assets and average equity, as the case may be, for that period. The Company has calculated its pro forma return on average assets and pro forma return on average equity for a period by calculating its pro forma net income for that period as described in note 1 above and dividing that by its average assets and 36 average equity, as the case be, for that period. The Company calculates its average assets and average equity for a period by dividing the sum of its total asset balance or total stockholder’s equity balance, as the case may be, as of the close of business on each day in the relevant period and dividing by the number of days in the period. The Company calculates its return on average common equity by excluding the preferred stock dividends to derive at net income available to common shareholders and excluding the average balance of its Series A preferred stock from the total average equity to derive at common average equity. Net interest margin for a period represents net interest income for that period divided by average interest-earning assets for that period. Efficiency ratio for a period represents noninterest expenses, excluding the amortization of core deposit intangibles, for that period divided by the sum of net interest income and noninterest income for that period. The Company calculates its dividend payout ratio for each period presented as the dividends paid per share for such period (excluding cash distributions made to shareholders in connection with tax liabilities as described in note (3) above) divided by its basic earnings per share for such period. (7) (8) (9) (10) Nonperforming loans include nonaccrual loans, loans past due 90 days or more and still accruing interest, and accruing loans modified under troubled debt restructurings. (11) Prior to 2015, the Company calculated its risk-weighted assets using the standardized method of the Basel II Framework, as implemented by the Federal Reserve and the FDIC. Beginning January 1, 2015, the Company calculated its risk-weighted assets using the Basel III Framework. The common equity tier 1 capital to risk-weighted assets ratio was a new ratio required under the Basel III Framework, effective January 1, 2015. This ratio is not applicable for periods prior to January 1, 2015. (12) The Company calculates common equity as of the end of the period as total stockholders' equity less the preferred stock at period end. (13) Excludes mortgage purchase loans 37 ITEM 7.

We urge you to consider all of these risks, uncertainties and other factors carefully in evaluating all such forward-looking statements that we may make. As a result of these and other matters, including changes in facts and assumptions not being realized, 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 by the Company in any report, filing, press release, document, report or announcement speaks only as of the date on which it is made. The Company undertakes no obligation to update any 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 it has chosen these assumptions or bases in good faith and they are reasonable. However, the Company 39 cautions you that assumptions or bases almost always vary from actual results, and the differences between assumptions or bases and actual results can be material. The Company undertakes no obligation to publicly update or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Overview The Company was organized as a bank holding company in 2002. On January 1, 2009, the Company merged with Independent Bank Group Central Texas, Inc., and, since that time, the Company has pursued a strategy to create long-term shareholder value through organic growth and through selective acquisitions of complementary banking institutions with operations in the Company’s market areas or in new market areas, such as Colorado. On April 8, 2013, the Company consummated the initial public offering of its common stock which is traded on the Nasdaq Global Select Market. The Company’s principal business is lending to and accepting deposits from businesses, professionals and individuals. The Company conducts all of the Company’s banking operations through Independent Bank. The Company derives its income principally from interest earned on loans and, to a lesser extent, income from securities available for sale. The Company also derives income from noninterest sources, such as fees received in connection with various deposit services and retail mortgage operations. From time to time, the Company also realizes gains on the sale of assets. The Company’s principal expenses include interest expense on interest-bearing customer deposits, advances from the Federal Home Loan Bank of Dallas, or FHLB, and other borrowings, operating expenses, such as salaries, employee benefits, occupancy costs, data processing and communication costs, expenses associated with other real estate owned, other administrative expenses, provisions for loan losses and the Company’s assessment for FDIC deposit insurance and acquisition expenses. The Company intends for this discussion and analysis to provide the reader with information that will assist in understanding the Company’s financial statements, the changes in certain key items in those financial statements from period to period and the primary factors that accounted for those changes. This discussion relates to the Company and its consolidated subsidiaries and should be read in conjunction with the Company’s consolidated financial statements as of December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 2015, and the accompanying notes, appearing elsewhere in this Annual Report on Form 10-K. The Company’s year ends on December 31. 40 Certain Events Affect Year-over-Year Comparability Acquisitions The Company completed one acquisition in 2017 and one acquisition in 2015. There were no acquisitions completed in 2016. These acquisitions increased total assets, gross loans and deposits on their respective acquisition date as detailed below. (dollars in millions) Grand Bank Carlile Bancshares, Inc. Acquisition Date Total Assets Gross Loans November 1, 2015 April 1, 2017 $620.2 2,444.2 $274.4 1,384.2 Deposits $523.7 1,825.2 The Company issued an aggregate 10,084,231 shares of common stock in connection with these acquisitions. In addition, the Company issued 448,500 and 400,000 shares of common stock in 2017 and 2016, respectively, to enhance our capital position. The comparability of the Company’s consolidated results of operations for the years ended December 31, 2017, 2016 and 2015 are affected by these acquisitions and stock issuances. At December 31, 2017, the acquisition of Integrity Bancshares, Inc. was pending. This transaction is expected to close in the second or third quarter of 2018. For more information on this acquisition, see the Pending Acquisition of Integrity Bancshares, Inc. section as discussed in Part I, Item 1. Business. Discussion and Analysis of Results of Operations The following discussion and analysis of the Company’s results of operations compares its results of operations for the years ended December 31, 2017, 2016 and 2015. Results of Operations The Company’s net income available to common shareholders increased by $23.0 million, or 42.9%, to $76.5 million ($2.97 per common share on a diluted basis) for the year ended December 31, 2017, from $53.5 million ($2.88 per common share on a diluted basis) for the year ended December 31, 2016. The increase resulted from a $97.9 million increase in interest income and a $21.7 million increase in noninterest income, partially offset by a $16.2 million increase in interest expense, a $63.0 million increase in noninterest expense and an $18.6 million increase in income tax expense. The Company’s net income for the year ended December 31, 2017, and, therefore, the Company’s return on average assets and the Company’s return on average equity, were adversely affected by $12.9 million of acquisition-related expenses related to the Carlile acquisition as well as the one- time remeasurement charge of $5.5 million to deferred taxes as a result of the enactment of the Tax Cuts and Jobs Act in late 2017. The Company posted returns on average common equity of 6.71% and 8.42%, returns on average assets of 0.96% and 0.98%, and efficiency ratios of 56.13% and 54.99% for the years ended December 31, 2017 and 2016, respectively. The efficiency ratio is calculated by dividing total noninterest expense (which does not include the provision for loan losses and the amortization of core deposits intangibles) by net interest income plus noninterest income. The Company’s dividend payout ratio was 13.42% and 11.76% and the equity to assets ratio was 15.38% and 11.49% for the years ended December 31, 2017 and 2016, respectively. The Company’s net income available to common shareholders increased by $15.0 million, or 38.9%, to $53.5 million ($2.88 per common share on a diluted basis) for the year ended December 31, 2016, from $38.5 million ($2.21 per common share on a diluted basis) for the year ended December 31, 2015. The increase resulted from a $36.0 million increase in interest income and a $3.4 million increase in noninterest income, partially offset by a $6.3 million increase in the interest expense, a $10.6 million increase in noninterest expense and a $7.6 million increase in income tax expense. The Company’s net income for the year ended December 31, 2016, and, therefore, the Company’s return on average assets and the Company’s return on average equity, were adversely affected by $1.5 million of acquisition-related expenses and $2.5 million of senior leadership restructuring expenses. The Company posted returns on average common equity of 8.42% and 7.13%, returns on average assets of 0.98% and 0.88%, and efficiency ratios of 54.99% and 59.71% for the years ended December 31, 2016 and 2015, respectively. The efficiency ratio is calculated by dividing total noninterest expense (which does not include the provision for loan losses and the amortization of core deposits intangibles) by net interest income plus noninterest income. The Company’s dividend payout ratio was 11.76% and 14.35% and the equity to assets ratio was 11.49% and 11.94% for the years ended December 31, 2016, and 2015, respectively. 41 Net Interest Income The Company’s net interest income is its interest income, net of interest expenses. Changes in the balances of the Company’s earning assets and its deposits, FHLB advances and other borrowings, as well as changes in the market interest rates, affect the Company’s net interest income. The difference between the Company’s average yield on earning assets and its average rate paid for interest-bearing liabilities is its net interest spread. Noninterest-bearing sources of funds, such as demand deposits and stockholders’ equity, also support the Company’s earning assets. The impact of the noninterest-bearing sources of funds is reflected in the Company’s net interest margin, which is calculated as annualized net interest income divided by average earning assets. The Company earned net interest income of $265.5 million for the year ended December 31, 2017, an increase of $81.7 million, or 44.4%, from $183.8 million for the year ended December 31, 2016. The increase in net interest income from the previous year was due to increased average earning asset balances resulting primarily from the acquisition of Carlile, as well as organic growth for the year. The Company’s net interest margin for 2017 increased to 3.84% from 3.81% in 2016, and the Company’s interest rate spread for 2017 decreased to 3.62% from the 3.66% interest rate spread for 2016. The average balance of interest-earning assets for 2017 increased by $2.1 billion, or 43.6%, to $6.9 billion from an average balance of $4.8 billion for 2016. The increase from prior year is due primarily to $1.8 billion in average earning assets acquired in the Carlile transaction as well as organic growth of 12.2% for the year. The Company’s net interest margin for the year ended December 31, 2017 was positively impacted by a nine basis point increase in the weighted-average yield on interest-earning assets to 4.45% for the year ended December 31, 2017, from 4.36% for the year ended December 31, 2016. The increase from the prior year is due primarily to loans and taxable securities acquired in the Carlile transaction, which had higher effective interest rates as well as higher loan accretion income and higher interest rates on interest-bearing deposits that are tied to the Fed Funds rate, which increased three times during 2017. The cost of interest bearing liabilities, including borrowings, was 0.83% for the year ended December 31, 2017 compared to 0.70% for the year ended December 31, 2016. The increase from the prior year is primarily due to higher rates offered on public fund certificates of deposit and money market accounts due to competition in our markets but also due in part to overall increased interest rates on deposit products, as well as short-term FHLB advances used for liquidity, which were both tied to Fed Funds rates. The Company earned net interest income of $183.8 million for the year ended December 31, 2016, an increase of $29.7 million, or 19.3%, from $154.1 million for the year ended December 31, 2015. The increase in net interest income was primarily due to growth of the Company’s average interest-earning assets during the year. The Company’s net interest margin for 2016 decreased to 3.81% from 4.05% in 2015, and the Company’s interest rate spread for 2016 decreased to 3.66% from the 3.89% interest rate spread for 2015. The average balance of interest-earning assets for 2016 increased by $1.0 billion, or 26.6%, to $4.8 billion from an average balance of $3.8 billion for 2015. The increases in interest-earning assets during the year was primarily due to strong organic loan growth of 14.6% for the year but also due in part to assets acquired during the fourth quarter 2015. The Company’s net interest margin for the year ended December 31, 2016 was adversely affected by a 21 basis point decline in the weighted-average yield on interest-earning assets to 4.36% for the year ended December 31, 2016, from 4.57% for the year ended December 31, 2015. This decline in yield reflects an increase in the Company's variable rate loan fundings during the second half of 2016 which resulted from changes in market interest rates and the competitive lending landscape. 42 Average Balance Sheet Amounts, Interest Earned and Yield Analysis. The following table presents average balance sheet information, interest income, interest expense and the corresponding average yields earned and rates paid for the years ended December 31, 2017, 2016 and 2015. The average balances are principally daily averages and, for loans, include both performing and nonperforming balances.

Net interest margins for the periods presented represent: (i) the difference between interest income on interest-earning assets and the interest expense on interest-bearing liabilities, divided by (ii) average interest-earning assets for the period. 43 Interest Rates and Operating Interest Differential. Increases and decreases in interest income and interest expense result from changes in average balances (volume) of interest-earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following table shows the effect that these factors had on the interest earned on the Company’s interest- earning assets and the interest incurred on the Company’s interest-bearing liabilities. The effect of changes in volume is determined by multiplying the change in volume by the previous year’s average rate. Similarly, the effect of rate changes is calculated by multiplying the change in average rate by the prior year’s volume. For purpose of the following table, changes attributable to both volume and rate, which cannot be segregated, have been allocated to the changes due to volume and the changes due to rate in proportion to the relationship of the absolute dollar amount of change in each. $ $ $ (dollars in thousands) Interest-earning assets Loans Taxable securities Nontaxable securities Federal funds sold and other Total interest-earning assets Interest-bearing liabilities Checking accounts Savings accounts Limited access money market accounts Certificates of deposit Total deposits FHLB advances Notes payable, repurchase agreements and other borrowings Junior subordinated debentures Total interest-bearing liabilities Net interest income For the Year Ended December 31, 2017 vs. 2016 For the Year Ended December 31, 2016 vs. 2015 Increase (Decrease) Due to Volume Rate Total Increase (Decrease) Increase (Decrease) Due to Volume Rate Total Increase (Decrease) 80,823 $ 5,957 $ 86,780 $ 37,476 $ (3,403) $ 34,073 $ $ 4,094 2,043 1,070 88,030 4,266 169 1,022 1,387 6,844 174 1,730 288 9,036 $ $ 1,454 66 2,358 9,835 1,269 (49) 3,235 1,144 5,599 1,565 (260) 253 7,157 $ $ 5,548 2,109 3,428 97,865 5,535 120 4,257 2,531 12,443 1,739 1,470 541 16,193 $ $ 1,067 127 861 39,531 2,044 12 350 (71) 2,335 2,400 576 — 5,311 (554) (142) 590 (3,509) $ 77 $ (15) 732 922 1,716 (1,358) 563 82 1,003 $ 78,994 $ 2,678 $ 81,672 $ 34,220 $ (4,512) $ 513 (15) 1,451 36,022 2,121 (3) 1,082 851 4,051 1,042 1,139 82 6,314 29,708 Interest Income. The Company’s total interest income increased $97.9 million, or 46.6%, to $307.9 million for the year ended December 31, 2017, from $210.0 million for the year ended December 31, 2016. The Company’s total interest income increased $36.0 million, or 20.7%, to $210.0 million for the year ended December 31, 2016 from $174.0 million for the year ended December 31, 2015. The following tables set forth the major components of the Company’s interest income for the years ended December 31, 2017, 2016 and 2015 and the period-over-period variations in such categories of interest income: (dollars in thousands) Interest income Interest and fees on loans Interest on taxable securities Interest on nontaxable securities Interest on interest-bearing deposits and other For the Year Ended December 31, 2017 2016 Variance 2017 v. 2016 For the Year Ended December 31, 2016 2015 Variance 2016 v. 2015 $ 290,357 $ 203,577 $ 86,780 42.6% $ 203,577 $ 169,504 $ 34,073 8,229 3,877 5,451 2,681 1,768 2,023 5,548 2,109 3,428 206.9% 119.3% 169.5 2,681 1,768 2,023 2,168 1,783 572 513 (15) 20.1% 23.7 (0.8) 1,451 253.7 Total interest income $ 307,914 $ 210,049 $ 97,865 46.6% $ 210,049 $ 174,027 $ 36,022 20.7% The Company’s interest and fees on loans increased 42.6% for the year ended December 31, 2017, compared to the year ended December 31, 2016, and was primarily attributable to a $1.6 billion increase in the average balance of the Company’s loans to $5.9 billion during the year ended 2017 as compared with the average balance of $4.2 billion for the year ended 2016. The increase primarily resulted from $1.4 billion loans held for investment that were acquired in the Carlile acquisition and strong organic growth in the Company’s loan portfolio of 12.2% for the year. The 20.1% increase in the Company’s interest and fees on loans for the year ended December 31, 2016, from the year ended December 31, 2015 was primarily attributable to a $778.2 million increase in the average balance of the Company’s loans to $4.2 billion during the year ended 2016 as compared with the average balance of $3.5 billion for the year ended 2015. The 44 increase primarily resulted from strong organic growth in the Company’s loan portfolio of 14.6% for the year but also due in part to assets acquired during the fourth quarter 2015. The interest the Company earned on taxable securities, which consists primarily of government agency and residential pass- through securities, increased 206.9% for the year ended December 31, 2017 from the year ended December 31, 2016 as a result of an increase in the average portfolio balance from $221.9 million for the year ended December 31, 2016 to $481.3 million for the year ended December 31, 2017. This increase was primarily attributable to the taxable securities acquired through the Carlile acquisition which had higher effective interest rates. The interest the Company earned on taxable securities increased 23.7% for the year ended December 31, 2016, due primarily to a 58.6% increase in the average balance of taxable securities from $139.9 million for the year ended December 31, 2015 to $221.9 million for the year ended December 31, 2016. The interest the Company earned on nontaxable securities increased 119.3% for the year ended December 31, 2017 as a result of an 111.6% increase in the average balance of nontaxable securities from $74.2 million for the year ended December 31, 2016 to $157.1 million for the year ended December 31, 2017, primarily related to the nontaxable securities acquired in the Carlile acquisition. The interest the Company earned on nontaxable securities during 2016 remained fairly consistent with 2015. The 169.5% increase in the Company's interest on interest-bearing deposits and other for the year ended December 31, 2017, from the year ended December 31, 2016 was primarily attributable to a 41.2% increase in the average balance from $290.3 million for the year ended December 31, 2016 to $410.0 million for the year ended December 31, 2017. The increase was primarily a result of balances acquired in the Carlile acquisition as well as higher interest rates on interest-bearing deposits which are tied to the Fed Funds rate. Interest Expense. Total interest expense on the Company’s interest-bearing liabilities increased $16.2 million, or 61.7%, to $42.4 million for the year ended December 31, 2017, from $26.2 million in the prior year. Total interest expense on the Company’s interest-bearing liabilities increased $6.3 million, or 31.7%, to $26.2 million for 2016 from $19.9 million for 2015. The following table sets forth the major components of the Company’s interest expense for the years ended December 31, 2017, 2016 and 2015 and the period-over-period variations in such categories of interest expense: (dollars in thousands) Interest Expense Interest on deposits Interest of FHLB advances Interest on repurchase agreements and other borrowings Interest on junior subordinated debentures For the Year Ended December 31, 2017 2016 Variance 2017 v. 2016 For the Year Ended December 31, 2016 2015 Variance 2016 v. 2015 $ 28,518 $ 16,075 $ 12,443 77.4% $ 16,075 $ 12,024 $ 5,858 6,898 1,162 4,119 5,428 621 1,739 1,470 541 42.2 27.1 87.1 4,119 5,428 621 3,077 4,289 539 4,051 1,042 1,139 82 33.7% 33.9 26.6 15.2 Total interest expense $ 42,436 $ 26,243 $ 16,193 61.7% $ 26,243 $ 19,929 $ 6,314 31.7% Interest expense on deposits for 2017 increased by $12.4 million, or 77.4%, primarily as a result of a 41.9% year-over-year increase in the average balance on the Company’s interest-bearing deposit accounts from $3.2 billion in 2016 to $4.5 billion in 2017 resulting from $1.2 billion of interest-bearing deposits acquired in the Carlile acquisition as well as organic growth. The average rate on the Company’s deposits increased by 12 basis points to 0.63% on average interest-bearing deposits for the year ended 2017, from 0.51% on average interest-bearing deposits for the year ended 2016. This increase in cost of funds for this source of funding primarily resulted from higher rates offered on public fund certificates of deposit and money market accounts due to competition in our markets but also due in part to increased interest rates on deposit products tied to Fed Funds rates and short-term FHLB advances. Interest expense on deposits for 2016 increased by $4.1 million, or 33.7%, primarily as a result of a 21.8% year-over-year increase in the average balance on the Company’s interest-bearing deposit accounts from $2.6 billion in 2015 to $3.2 billion in 2016 resulting from organic growth as well as deposits acquired in the November 2015 acquisition. The average rate on the Company’s deposits increased by 5 basis points to 0.51% on average interest-bearing deposits for the year ended 2016, from 0.46% on average interest-bearing deposits for the year ended 2015. This increase in cost of funds for this source of funding primarily resulted from higher variable interest rates on brokered money market accounts and public fund time deposits which tend to be more rate sensitive. Interest expense on FHLB advances for 2017 increased by $1.7 million, or 42.2%, due primarily to a higher average balance of such advances over the period, from $465.0 million in 2016 to $483.9 million in 2017, resulting from the use of short term FHLB advances for liquidity needs during the applicable period. 45 Interest expense on FHLB advances for 2016 increased by $1.0 million, or 33.9%, due primarily to a higher average balance of such advances over the period, from $225.9 million in 2015 to $465.0 million in 2016. Interest expense on other borrowings and repurchase agreements for the year ended December 31, 2017 increased by $1.5 million, or 27.1% from the year ended December 31, 2016, primarily as a result of a full year's interest expense recognized on $45 million subordinated debt issued in 2016 in addition to a higher average balance of such borrowings. The average balance of the Company’s other borrowings increased by $29.2 million primarily as a result of the Company's issuance of $30 million in 5.0% fixed and floating rate subordinated debentures in a public offering during fourth quarter 2017 to provide additional capital to the Bank to support growth. Interest expense on other borrowings and repurchase agreements for the year ended 2016 increased by $1.1 million, or 26.6%, primarily as a result of a higher average balance of such borrowings. The average balance of the Company’s notes payable and other borrowings increased by $9.9 million primarily as a result of an increase in the Company’s subordinated debentures. The Company issued an additional $45 million of its subordinated debt in a public offering in June 2016 to provide additional capital to the Bank to support growth. Interest expense on the additional subordinated debt totaled $1.3 million for the year ended December 31, 2016. This increase in interest expense was partially offset by the effect of $12.1 million in repurchase agreements held as December 31, 2015 which were transferred to deposit accounts during 2016 and the repayment of $5.8 million in principal amounts of subordinated debt during the year ended December 31, 2016. Provision for Loan Losses Management actively monitors the Company’s asset quality and provides specific loss provisions when necessary. Provisions for loan losses are charged to income to bring the total allowance for loan losses to a level deemed appropriate by management based on such factors as historical loss experience, trends in classified loans and past dues, the volume and growth in the loan portfolio, current economic conditions and the value of collateral. Loans are charged off against the allowance for loan losses when appropriate. Although management believes it uses the best information available to make determinations with respect to the provision for loan losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the determination. The Company increased its allowance for loan losses to $39.4 million at December 31, 2017, by making provisions for loan losses totaling $8.3 million during the year ended December 31, 2017. This is a decrease of $1.2 million, or 12.4% in provision expense compared to total provision expense of $9.4 million made by the Company in 2016. Provision expense is primarily reflective of organic loan growth and net charge-offs during the year. The decrease from prior year primarily reflects the improved credit quality of our energy portfolio. Offsetting the increase to the allowance balance were net charge-offs totaling $454 thousand for 2017, which is 0.01% of the Company's average loans outstanding during the period. The Company increased its allowance for loan losses to $31.6 million at December 31, 2016, by making provisions for loan losses totaling $9.4 million during the year ended December 31, 2016. This is an increase of $209 thousand, or 2.3% in provision expense over the total provision expense of $9.2 million made by the Company in 2015. Provision expense is primarily reflective of organic loan growth during the year as well as increased reserve allocations related to the risks associated with the energy portfolio due to commodity price volatility during the majority of 2016. Offsetting the increase to the allowance balance were net charge-offs totaling $4.9 million for 2016, which is 0.12% of the Company's average loans outstanding during the period. The 2016 charge-offs were primarily on energy related credits which had been reserved during late 2015 and early 2016. The balance of the provision for loan losses was made based on the Company’s assessment of the credit quality of the Company’s loan portfolio and in view of the amount of the Company’s net charge-offs in that period. The Company did not make any provision for loan losses with respect to the loans acquired in the Carlile acquisition completed on April 1, 2017 because, in accordance with acquisition accounting standards, the Company recorded the loans acquired in the acquisitions at fair value without a reserve and determined that the Company’s fair value adjustments appropriately reflected the probability of losses on those loans as of the acquisition date. The Company does not believe there has been any deterioration of credit of these acquired loans since these acquisition and has not recorded a subsequent provision. The Company will begin phasing the acquired portfolio into the allowance allocation as acquired loans are renewed in 2018. As of December 31, 2017, the discount on acquired loans totaled $24.6 million. 46 Noninterest Income The following table sets forth the major components of noninterest income for the years ended December 31, 2017, 2016 and 2015 and the period-over-period variations in such categories of noninterest income: (dollars in thousands) Noninterest Income Service charges on deposit accounts Mortgage banking revenue Gain on sale of loans Gain (loss) on sale of branches (Loss) gain on sale of other real estate Gain on sale of repossessed assets Gain on sale of securities available for sale (Loss) gain on sale of premises and equipment Increase in cash surrender value of bank owned life insurance All other noninterest income Total noninterest income N/M - not meaningful For the Year Ended December 31, Variance For the Year Ended December 31, 2017 2016 2017 v. 2016 2016 2015 Variance 2016 v. 2015 $ 12,955 $ 7,222 $ 13,755 7,038 351 2,917 (160) 1,010 124 (21) 2,748 7,608 — (43) 57 — 4 32 1,348 3,897 5,733 6,717 351 2,960 (217) 1,010 120 (53) 1,400 3,711 79.4% $ 7,222 $ 6,898 $ 95.4 100.0 N/M N/M 100.0 N/M N/M 103.9 95.2 7,038 5,269 — (43) 57 — 4 32 1,348 3,897 116 — 290 — 134 (358) 1,077 2,702 $ 41,287 $ 19,555 $ 21,732 111.1% $ 19,555 $ 16,128 $ 324 1,769 (116) (43) (233) — (130) 390 271 1,195 3,427 4.7% 33.6 (100.0) (100.0) (80.3) — (97.0) N/M 25.2 44.2 21.2% Noninterest income increased $21.7 million, or 111.1%, to $41.3 million for the year ended 2017 from $19.6 million for the year ended 2016. Total noninterest income increased $3.4 million, or 21.2%, for the year ended December 31, 2016, compared to the year ended December 31, 2015. Significant changes in the components of noninterest income are discussed below. Service Charges. Service charges on deposit accounts increased $5.7 million, or 79.4%, for the year ended December 31, 2017, as compared to the same period in 2016. The increase in service charges reflects an increase in deposit accounts due to organic growth and to the acquisition of Carlile in April 2017. In addition, the Company implemented a new deposit fee schedule in late 2016 which increased organic service charges for the year over year period. Service charges on deposit accounts for the year ended December 31, 2016 increased $324 thousand, or 4.7%, compared to the year ended December 31, 2015. The increase during 2016 is due to an increase in deposits accounts primarily due to acquisition growth in late 2015. Mortgage Banking Revenue. Mortgage banking revenue for the year ended December 31, 2017 increased $6.7 million, or 95.4%, over the same period in 2016. This increase is primarily reflective of the retail mortgage line of business acquired with the Carlile acquisition. Mortgage banking revenue for the year ended December 31, 2016 increased $1.8 million, or 33.6%, compared to the comparable period in 2015. The increase in both years is also reflective of the housing market growth and home purchase activity in our Austin and north Texas markets. Gain (Loss) on Sale of Branches. Gain (loss) on sale of branches was $2.9 million for the year ended December 31, 2017. This net gain relates to the sale of one Texas branch and nine Colorado branches to two unaffiliated institutions during third and fourth quarter of 2017 as a result of integrating and restructuring the Northstar branch system acquired in the Carlile acquisition. Gain on Sale of Repossessed Assets. Gain on sale of repossessed assets was $1.0 million for the year ended December 31, 2017. The gain was the result of a sale of a previously charged off repossessed asset acquired in the Carlile acquisition. Increase in Cash Surrender Value of Bank Owned Life Insurance. The cash surrender value of bank owned life insurance increased $1.4 million, or 103.9% from $1.3 million in 2016 to $2.7 million in 2017. The increase is a result of $53.2 million in policies acquired in the Carlile transaction. The cash surrender value of bank owned life insurance increased $271 thousand, or 25.2% from $1.1 million in 2015 to $1.3 million in 2016. The increase is a result of $15 million in policies purchased in June 2016. Other Noninterest Income. Other noninterest income increased $3.7 million, or 95.2%, for the year ended December 31, 2017 compared to the same period in 2016. The increase is primarily related to acquired loan recoveries as well as income related to the mortgage warehouse purchase loans line of business acquired with Carlile acquisition, in addition to increased merchant card income and earnings credits on correspondent accounts. Other noninterest income increased $1.2 million, or 44.2%, for 47 the year ended December 31, 2016 compared to the same period in 2015. The increase is primarily related to increased earning credits on correspondent accounts, increased wealth management income and increased bank card merchant income. Noninterest Expense Noninterest expense increased $63.0 million, or 55.4%, to $176.8 million for the year ended 2017 from $113.8 million for the year ended 2016. The increase from 2016 to 2017 is primarily due to increases in salaries and benefits expenses, occupancy, data processing expenses, other real estate, acquisition expenses and other noninterest expenses.The increases primarily reflect increased expenses related to the Carlile acquisition completed on April 1, 2017 and also due to organic growth within the Company. Noninterest expense increased $10.6 million, or 10.3%, to $113.8 million for the year ended 2016 from $103.2 million for the year ended 2015. The increase from 2015 to 2016 is primarily due to increases in salaries and benefits expenses, data processing expenses, FDIC assessment and other noninterest expenses due to organic growth within the Company but also due to a full year of expenses from the acquisition in November 2015. The following table sets forth the major components of the Company’s noninterest expense for the years ended December 31, 2017, 2016 and 2015, and the period-over-period variations in such categories of noninterest expense: (dollars in thousands) Noninterest Expense For the Year Ended December 31, Variance For the Year Ended December 31, 2017 2016 2017 v. 2016 2016 2015 Variance 2016 v. 2015 Salaries and employee benefits $ 95,741 $ 66,762 $ 28,979 43.4% $ 66,762 $ 60,541 $ 6,221 10.3% Occupancy Data processing FDIC assessment Advertising and public relations Communications Other real estate owned expense, net Impairment of other real estate Core deposit intangible amortization Professional fees Acquisition expense, including legal Other Total noninterest expense N/M - not meaningful 22,079 16,101 8,597 4,311 1,452 2,860 304 1,412 4,639 4,564 12,898 17,956 4,752 3,889 1,107 2,116 205 106 1,964 3,212 1,517 12,059 5,978 3,845 422 345 744 99 1,306 2,675 1,352 11,381 5,897 37.1 80.9 10.9 31.2 35.2 48.3 N/M 136.2 42.1 750.2 48.9 16,101 16,058 4,752 3,889 1,107 2,116 205 106 1,964 3,212 1,517 3,384 2,259 1,038 2,219 169 35 1,555 3,191 1,420 12,059 11,329 43 1,368 1,630 69 (103) 36 71 409 21 97 730 0.3 40.4 72.2 6.6 (4.6) 21.3 N/M 26.3 0.7 6.8 6.4 $ 176,813 $ 113,790 $ 63,023 55.4% $ 113,790 $ 103,198 $ 10,592 10.3% Salaries and Employee Benefits. Salaries and employee benefits expense, which historically has been the largest component of the Company’s noninterest expense, increased $29.0 million, or 43.4%, for the year ended December 31, 2017, compared to the year ended December 31, 2016. The increase is primarily due to an increase in the number of the Company's full-time equivalent employees both resulting from the acquisition of Carlile and organic growth within the Company. The increase is also due to severance and retention bonuses paid to Carlile/Northstar employees during the year. In addition, commissions paid to our mortgage lenders increased related to increased activity in our retail mortgage line of business, also primarily as a result of the Carlile acquisition. Salaries and employee benefits expense increased $6.2 million, or 10.3%, for the year ended December 31, 2016, compared to the year ended December 31, 2015. The increase is primarily due to approximately $2.6 million in compensation costs recognized during the second quarter of 2016 relating to the Company's senior leadership restructure of which $2 million related to the former Houston Region CEO's Separation Agreement, increased bonuses related to mortgage production, and a full year of Grand Bank employees' salaries. Occupancy Expense. Occupancy expense increased $6.0 million, or 37.1%, for the year ended December 31, 2017, compared to the year ended December 31, 2016. The increase is reflective of additional branches acquired in the Carlile transaction. Occupancy expense remained consistent as of December 31, 2016 compared to the same period in 2015. 48 Data Processing. Data processing fees increased $3.8 million, or 80.9%, for the year ended December 31, 2017, compared to the same period in 2016. The increase over the same prior period is reflective of increased costs directly related to the Carlile transaction due to the additional accounts, employees and locations added, but also due to maintaining two core systems from close until the conversion was completed in early fourth quarter 2017. Data processing fees increased $1.4 million, 40.4%, for the year ended December 31, 2016, compared to the same period in 2015. The change is due to increased online banking fees and other costs related directly to an increase in accounts as well as added employees and locations over the same period prior year, related both to organic growth and growth through the Grand acquisition in 2015. FDIC Assessment. FDIC assessment expense increased $422 thousand, or 10.9%, for the year ended December 31, 2017, compared to the same period in 2016 and increased $1.6 million, or 72.2% for the year ended December 31, 2016 compared to the same period in 2015. The increase is due to a higher assessment associated with an increase in deposit accounts, both due to organic growth and growth through acquisitions. Impairment of Other Real Estate. Impairment of other real estate increased $1.4 million for the year ended December 31, 2017 compared to the same period in 2016. The increase is primarily related to an impairment of a Houston branch location , which was transferred from bank premises to other real estate owned when it was closed in the third quarter of 2017. Core Deposit Intangible Amortization. Core deposit intangible amortization increased $2.7 million, or 136.2%, for the year ended December 31, 2017 compared to the same period in 2016. The increase is due to the increase of $36.7 million in core deposit intangibles recorded in connection with the Carlile transaction. Professional Fees. Professional fees increased $1.4 million, or 42.1%, for the year ended December 31, 2017 compared to the same period in 2016. The increase is mainly due to increased consulting fees related to data processing projects and mortgage banking disclosure agreements in addition to legal fees associated with existing litigation inherited in the Carlile transactions as well as increased legal fees related to workouts on acquired Carlile loans, other real estate property and repossessed assets. Acquisition Expense. Acquisition expense is primarily legal, advisory and accounting fees associated with services to facilitate the acquisition of other banks. Acquisition expenses also include data processing conversion costs and contract termination costs. Total acquisition expenses for the year ended December 31, 2017, increased $11.4 million, or 750.2% over the same period in 2016. The total acquisition expense in 2016 increased $97 thousand, or 6.8% over the same period in 2015. The change in the respective period is directly related to the acquisition activity in those periods. The Company incurred expenses related to the announced acquisition of Integrity Bancshares, Inc. in late 2017, the completed acquisition of Carlile Bancshares Inc. in April 2017 and closed one acquisition in late 2015. Other. Other noninterest expense for the year ended December 31, 2017 increased by $5.9 million, or 48.9%, compared to the same period in 2016. Other noninterest expense increased by $730 thousand, or 6.4%, for the year ended December 31, 2016, compared to the same period in 2015. The majority of the increase for each period relates to general increases in operations due to organic growth within the Company as well as acquisition activity occurring in April 2017 and November 2015. Income Tax Expense Income tax expense was $45.2 million for the year ended December 31, 2017, which is an effective tax rate of 37.1%. Income tax expense was $26.6 million for the year ended December 31, 2016, which is an effective tax rate of 33.2%. Income tax expense was $19.0 million for the year ended December 31, 2015, which is an effective tax rate of 32.9%. The effective income tax rates differed from the U.S. statutory federal income tax rate of 35% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies and discrete items including the income tax effects associated with stock-based compensation, non-deductible acquisition expenses, and changes in enacted tax rates. The effective tax rate for 2017 was impacted by the adjustment of our deferred tax assets and liabilities related to the reduction in the U.S. federal statutory income tax rate to 21% under the Tax Cuts and Jobs Act enacted on December 22, 2017. Under ASC 740, Income Taxes, the effect of income tax law changes on deferred taxes should be recognized as a component of income tax expense related to continuing operations in the period in which the law is enacted. The Company has completed its accounting under ASC 740 for all material deferred tax assets and liabilities. Provisional amounts have been recorded for certain immaterial items, such as Schedules K-1 from partnership investments and state apportionment. As a result of the reduction in the U.S. federal statutory income tax rate, we recognized additional tax expense of $5.5 million related to the remeasurement of deferred taxes based on the new income tax rate. Material adjustments to provisional amounts are not anticipated. 49 Also impacting the Company's effective tax rate for the 2017 period was the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, in the 2017 period, which requires that all income tax effects related to vestings of share-based payment awards be reported in earnings as an expense (or benefit) to income tax expense. Previously, excess income tax benefits of a vested award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits recognized in earnings during the awards vesting period. The requirement to report those income tax effects in earnings has been applied to vestings occurring on or after January 1, 2017 and resulted in recording a $1.3 million tax benefit for the year ended December 31, 2017. No valuation allowance for deferred tax assets was recorded at December 31, 2017, 2016 and 2015, as management believes it is more likely than not that all of the deferred tax assets will be realized.

Assets The Company's total assets increased by $2.8 billion, or 48.4%, to $8.7 billion as of December 31, 2017 from $5.9 billion at December 31, 2016 due to the Carlile acquisition and organic growth during the period. The Company's total assets increased by $797.8 million, or 15.8%, to $5.9 billion as of December 31, 2016 from $5.1 billion at December 31, 2015 due to organic growth during the period. Loan Portfolio The Company’s loan portfolio is the largest category of the Company’s earning assets. The following table presents the balance and associated percentage of each major category in the Company’s loan portfolio as of December 31, 2017, 2016, 2015, 2014 and 2013: (dollars in thousands) Amount % of Total Amount % of Total Amount % of Total Amount % of Total Amount % of Total 2017 2016 2015 2014 2013 Commercial Real estate: $ 1,059,984 16.3% $ 630,805 13.7% $ 731,818 18.3% $ 672,052 21.0% $ 241,178 14.0% Commercial 3,369,892 51.7 2,459,221 Commercial construction, land and land development Residential (1) Single family interim construction Agricultural Consumer Other 744,868 931,495 289,680 82,583 34,639 304 11.5 14.3 4.4 1.3 0.5 — 531,481 644,340 235,475 53,548 27,530 166 53.7 11.6 14.1 5.1 1.2 0.6 — 1,949,734 419,611 620,289 187,984 50,178 41,966 124 48.7 10.5 15.5 4.7 1.3 1.0 — 1,450,434 334,964 518,478 138,278 38,822 52,267 242 45.2 10.5 16.2 4.3 1.2 1.6 — 843,436 130,320 342,037 83,144 40,558 45,762 108 48.9 7.5 19.8 4.8 2.3 2.7 — 6,513,445 100.0% 4,582,566 100.0% 4,001,704 100.0% 3,205,537 100.0% 1,726,543 100.0% Deferred loan fees Allowance for loan losses (2,568) (39,402) (2,117) (31,591) (1,553) (27,043) (487) (18,552) — (13,960) Total loans, net $ 6,471,475 $ 4,548,858 $ 3,973,108 $ 3,186,498 $ 1,712,583 (1) Includes mortgage loans held for sale as of December 31, 2017, 2016, 2015, 2014 and 2013 of $39.2 million, $9.8 million, $12.3 million, $4.5 million and $3.4 million, respectively. As of December 31, 2017, the Company's loan portfolio, net of the allowance for loan losses and deferred fees, totaled $6.5 billion, which is an increase of 42.3% over total net loans at December 31, 2016 and for which increase was due to the Carlile acquisition and organic loan growth during the year. As of December 31, 2016, the Company's loan portfolio, net of the allowance for loan losses and deferred fees, totaled $4.5 billion, which is an increase of 14.5% over total net loans at December 31, 2015 and for which increase was due to organic loan growth during the year. The principal categories of the Company’s loan portfolio are discussed below: Commercial loans. The Company provides a mix of variable and fixed rate commercial loans. The loans are typically made to small-and medium-sized manufacturing, wholesale, retail, energy related service businesses and medical practices for working capital needs and business expansions. Commercial loans generally include lines of credit and loans with maturities of five years or less. The loans are generally made with operating cash flows as the primary source of repayment, but may also include collateralization by inventory, accounts receivable, equipment and/or personal guarantees. Additionally, our commercial loan portfolio includes loans made to customers in the energy industry, which is a complex, technical and cyclical industry. Experienced bankers with specialized energy lending experience originate our energy loans. Companies in this industry produce, extract, develop, exploit and explore for oil and natural gas. Loans are primarily collateralized with proven producing oil and gas reserves based on a technical evaluation of these reserves. In addition, with the acquisition of Carlile, the Company acquired a mortgage warehouse purchase program which provides a mortgage warehouse lending vehicle to third party mortgage bankers across a broad geographic scale. The mortgage loans are underwritten, in part, on approved investor takeout commitments. These loans are reported as commercial loans since the loans are secured by notes receivable, not real estate. 51 The Company’s commercial loan portfolio increased $429.2 million, or 68.0%, to $1.1 billion as of December 31, 2017, from $630.8 million as of December 31, 2016 and from $731.8 million at December 31, 2015. The increase in this portfolio type for the current year is primarily due to the loans acquired in the Carlile acquisition, including $164.7 million of mortgage warehouse purchase loans as well as organic loan growth. The decrease in commercial loans from 2015 to 2016 was primarily due to a decrease in the energy portfolio during 2016. The energy exploration and production (E&P) portfolio totaled $115.3 million, or approximately 2.5% as of December 31, 2016 and $182.5 million, or approximately 4.6% of the total portfolio at December 31, 2015. Commercial real estate loans. The Company’s commercial real estate loans generally are used by customers to finance their purchase of office buildings, retail centers, medical facilities and mixed-use buildings. Approximately 34%, 35% and 40% of the Company’s commercial real estate loans as of December 31, 2017, 2016, and 2015, respectively, were owner-occupied. Such loans generally involve less risk than loans on investment property. The Company expects that commercial real estate loans will continue to be a significant portion of the Company’s total loan portfolio and an area of emphasis in the Company’s lending operations. Commercial real estate loans increased $910.7 million, or 37.0%, to $3.4 billion as of December 31, 2017 from $2.5 billion as of December 31, 2016. The increase was due to the loans added in the Carlile acquisition as well as organic loan growth in this loan type during the year. Commercial real estate loans increased $509.5 million, or 26.1%, to $2.5 billion as of December 31, 2016 from $2.0 billion as of December 31, 2015. The increase was due to organic loan growth in this loan type during the year across all of our markets. Commercial construction, land and land development loans. The Company’s commercial construction, land and land development loans comprise loans to fund commercial construction, land acquisition and real estate development construction. Although the Company continues to make commercial construction loans, land acquisition and land development loans on a selective basis, the Company does not expect the Company’s lending in this area to result in this category of loans being a significantly greater portion of the Company’s total loan portfolio. Commercial construction, land and land development loans increased $213.4 million, or 40.1% to $744.9 million at December 31, 2017 from $531.5 million at December 31, 2016, due to the addition of the loans acquired through Carlile and through organic loan growth in this type of loan. The Company’s loans in this segment increased $111.9 million, or 26.7% to $531.5 million at December 31, 2016 from $419.6 million at December 31, 2015, due to organic loan growth in this type of loan. Residential Real Estate Loans. The Company’s residential real estate loans are primarily made with respect to and secured by single-family homes, which are both owner-occupied and investor owned and include a limited amount of home equity loans, with a relatively small average loan balance spread across many individual borrowers. The Company offers a variety of mortgage loan portfolio products which generally are amortized over five to 30 years. Loans collateralized by 1-4 family residential real estate generally have been originated in amounts of no more than 80% of appraised value. The Company requires mortgage title insurance and hazard insurance. The Company retains these portfolio loans for its own account rather than selling them into the secondary market. By doing so, the Company incurs interest rate risk as well as the risks associated with nonpayments on such loans. The Company’s loan portfolio also includes a number of multi-family housing real estate loans. The Company expects that the Company will continue to make residential real estate loans, with an emphasis on single- family housing loans, so long as housing values in the Company’s markets do not deteriorate from current prevailing levels and the Company is able to make such loans consistent with the Company’s current credit and underwriting standards. The Company’s residential real estate loan portfolio grew by $287.2 million, or 44.6%, to a balance of $931.5 million as of December 31, 2017 from $644.3 million as of December 31, 2016. The increase in this category was due to both organic loan growth and loans acquired in the Carlile transaction. This portfolio grew by $24.1 million, or 3.9%, to a balance of $644.3 million as of December 31, 2016 from $620.3 million as of December 31, 2015. Single-Family Interim Construction Loans. The Company makes single-family interim construction loans to home builders and individuals to fund the construction of single-family residences with the understanding that such loans will be repaid from the proceeds of the sale of the homes by builders or, in the case of individuals building their own homes, with the proceeds of a permanent mortgage loan. Such loans are secured by the real property being built and are made based on the Company’s assessment of the value of the property on an as-completed basis. The Company expects to continue to make single-family interim construction loans so long as demand for such loans continues and the market for single-family housing and the values of such properties remain stable or continue to improve in the Company’s markets. 52 The balance of single-family interim construction loans in the Company’s loan portfolio increased by $54.2 million, or 23.0%, to $289.7 million as of December 31, 2017 from the balance of $235.5 million as of December 31, 2016. The increase during the year was due to continuing new home activity as a result of continued low mortgage rates and through the loans acquired in the Carlile transaction. Single family interim construction loans increased by $47.5 million, or 25.3%, to $235.5 million as of December 31, 2016 from the balance of $188.0 million as of December 31, 2015. The increase during the year was due to continuing new home activity as a result of continued low mortgage rates. Other Categories of Loans. Other categories of loans included in the Company’s loan portfolio include agricultural loans made to farmers and ranchers relating to their operations, consumer loans made to individuals for personal purposes, including automobile purchase loans and personal loans. None of these categories of loans represents more than 2% of the Company’s total loan portfolio as of December 31, 2017, 2016, and 2015 and such categories continue to be a very small percentage of the Company's total loan portfolio. The following table sets forth the contractual maturities, including scheduled principal repayments, of the Company’s loan portfolio (which includes balloon notes) and the distribution between fixed and adjustable interest rate loans as of December 31, 2017: As of December 31, 2017 (dollars in thousands) Commercial Real estate: Commercial real estate Commercial construction, land and land development Residential real estate Single family interim construction Agricultural Consumer Other Total loans Asset Quality Within One Year Fixed Rate Adjustable Rate One Year to Five Years Adjustable Rate Fixed Rate After Five Years Total Fixed Rate Adjustable Rate Fixed Rate Adjustable Rate $ 249,190 $ 297,610 $ 208,874 $ 181,997 $ 23,029 $ 99,284 $ 481,093 $ 578,891 135,032 68,999 1,281,139 476,065 232,057 1,176,600 1,648,228 1,721,664 122,963 87,914 97,350 12,620 10,941 304 134,340 25,902 124,536 9,420 3,258 — 174,256 291,385 9,694 23,930 19,010 — 171,810 20,527 15,116 13,883 310 — 21,020 295,942 35,225 1,913 999 — 120,479 209,825 7,759 20,817 121 — 318,239 675,241 142,269 38,463 30,950 304 426,629 256,254 147,411 44,120 3,689 — $ 716,314 $ 664,065 $ 2,008,288 $ 879,708 $ 610,185 $ 1,634,885 $ 3,334,787 $ 3,178,658 Nonperforming Assets. The Company has established procedures to assist the Company in maintaining the overall quality of the Company’s loan portfolio. In addition, the Company has adopted underwriting guidelines to be followed by the Company’s lending officers and require significant senior management review of proposed extensions of credit exceeding certain thresholds. When delinquencies exist, the Company rigorously monitors the levels of such delinquencies for any negative or adverse trends. The Company’s loan review procedures include approval of lending policies and underwriting guidelines by Independent Bank’s board of directors, an annual independent loan review, approval of large credit relationships by Independent Bank’s Executive Loan Committee and loan quality documentation procedures. The Company, like other financial institutions, is subject to the risk that its loan portfolio will be subject to increasing pressures from deteriorating borrower credit due to general economic conditions. The Company discontinues accruing interest on a loan when management of the Company believes, after considering the Company’s collection efforts and other factors, that the borrower’s financial condition is such that collection of interest of that loan is doubtful. Loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans, including troubled debt restructurings, that are placed on nonaccrual status or charged off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The Company did not make any changes in the Company’s nonaccrual policy during the years of 2017, 2016 or 2015. Placing a loan on nonaccrual status has a two-fold impact on net interest earnings. First, it may cause a charge against earnings for the interest which had been accrued in the current year but not yet collected on the loan. Second, it eliminates future interest income with respect to that particular loan from the Company’s revenues. Interest on such loans is not recognized until the entire principal is collected or until the loan is returned to performing status. 53 Real estate the Company has acquired as a result of foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned until sold. The Company’s policy is to initially record other real estate owned at fair value less estimated costs to sell at the date of foreclosure. After foreclosure, other real estate is carried at the lower of the initial carrying amount (fair value less estimated costs to sell or lease), or at the value determined by subsequent appraisals or internal valuations of the other real estate. The Company obtains appraisals of real property that secure loans and may update such appraisals of real property securing loans categorized as nonperforming loans and potential problem loans, in each case as required by regulatory guidelines. In instances where updated appraisals reflect reduced collateral values, an evaluation of the borrower’s overall financial condition is made to determine the need, if any, for possible write-downs or appropriate additions to the allowance for loan losses. The Company periodically modifies loans to extend the term or make other concessions to help a borrower with a deteriorating financial condition stay current on their loan and to avoid foreclosure. The Company generally does not forgive principal or interest on loans or modify the interest rates on loans to rates that are below market rates. Under applicable accounting standards, such loan modifications are generally classified as troubled debt restructurings. 54 The following table sets forth the allocation of the Company’s nonperforming assets among the Company’s different asset categories as of the dates indicated. The Company classifies nonperforming loans (excluding loans acquired with deteriorated credit quality) as nonaccrual loans, loans past due 90 days or more and still accruing interest or loans modified under restructurings as a result of the borrower experiencing financial difficulties. The balances of nonperforming loans reflect the net investment in these assets, including deductions for purchase discounts.

(2) Excluding mortgage warehouse purchase loans of $164.7 million at December 31, 2017. The Company had $14.1 million, $15.6 million and $8.8 million in loans on nonaccrual status as of December 31, 2017, 2016, and 2015, respectively. The decrease from December 31, 2016 to December 31, 2017 was due to $5.8 million of nonaccrual payoffs offset by additions totaling $4.7 million during the year as well as the removal of a $1.0 million single-family interim 55 construction loan from nonaccrual status due to repossession of collateral. The increase from December 31, 2015 to December 31, 2016 was due to $10.8 million in loans being placed on nonaccrual during the year offset by a $3 million partial charge-off on an energy loan and other reductions in nonaccrual loans during the period. Troubled debt restructurings that were also on nonaccrual status (excluding loans acquired with deteriorated credit quality) totaled $1.0 million, $209 thousand, and $621 thousand at December 31, 2017, 2016, and 2015, respectively. Loans past due 90 days and still accruing totaled $136 thousand as of December 31, 2017. The Company did not recognize any interest income on nonaccrual loans during 2017, 2016 or 2015 while the loans were in nonaccrual status. The amount of interest the Company included in the Company’s net interest income for the years ended 2017, 2016 and 2015 with respect to nonperforming loans was $190 thousand, $207 thousand and $638 thousand, respectively. Additional interest income that the Company would have recognized on these nonperforming loans had they been current in accordance with their original terms was $911 thousand, $623 thousand and $329 thousand, respectively, during the years ended 2017, 2016 and 2015, respectively. As of December 31, 2017, the Company had a total of 89 loans with an aggregate principal balance of $35.9 million that were not currently impaired loans, nonaccrual loans, 90 days past due loans or troubled debt restructurings, but where the Company had information about possible credit problems of the borrowers that caused the Company’s management to have serious concerns as to the ability of the borrowers to comply with present loan repayment terms and that could result in those loans becoming nonaccrual loans, 90 days past due loans or troubled debt restructurings in the future. The Company generally continues to use the classification of acquired loans classified nonaccrual or 90 days and accruing as of the acquisition date. The Company does not classify acquired loans as troubled debt restructurings, or TDRs, unless the Company modifies an acquired loan subsequent to acquisition that meets the TDR criteria. Reported delinquency of the Company’s purchased loan portfolio is based upon the contractual terms of the loans. As of December 31, 2017, the Company had other real estate owned and other repossessed assets of $7.2 million, which is an increase from the balance of $2.0 million for prior year. The increase is a result of additions totaling $11.2 million related to the Carlile acquisition as well as $2.1 million in property additions, including the Houston branch closure, two foreclosures and capital improvements to single family interim properties, offset by dispositions totaling $7.8 million and $500 thousand in subsequent write-downs. As of December 31, 2016, the Company had other real estate owned of $2.0 million, which is a slight decrease from the balance of $2.2 million for prior year. This was due to decreased foreclosure and disposition activity during 2016. The Company utilizes an asset risk classification system in compliance with guidelines established by the state and federal banking regulatory agencies as part of the Company’s efforts to improve asset quality. In connection with examinations of insured institutions, examiners have the authority to identify problem assets and, if appropriate, classify them. There are three classifications for problem assets: “substandard,” “doubtful,” and “loss.” Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the insured institution will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full questionable and there is a high probability of loss based on currently existing facts, conditions and values. An asset classified as loss is not considered collectible and is of such little value that continuance as an asset is not warranted. The Company produces a problem asset report that is reviewed by Independent Bank’s board of directors monthly. That report also includes “pass/watch” loans and Special Mention. Pass/watch loans have a potential weakness that requires more frequent monitoring. Special Mention credits have weaknesses that require attention. Officers and senior management review these loans monthly to determine if a more severe rating is warranted. Allowance for Loan Losses. The allowance for loan losses is established through charges to earnings in the form of a provision for loan losses. The Company’s allowance for loan losses represents the Company’s estimate of probable and reasonably estimable loan losses inherent in loans held for investment as of the respective balance sheet date. The Company’s methodology for assessing the adequacy of the allowance for loan losses includes a general allowance for performing loans, which are grouped based on similar characteristics, and an allocated allowance for individual impaired loans. Actual credit losses or recoveries are charged or credited directly to the allowance. The Company establishes a general allowance for loan losses that the Company believes to be adequate for the losses the Company estimates to be inherent in the Company’s loan portfolio. In making the Company’s evaluation of the credit risk of the loan portfolio, the Company considers factors such as the volume, growth and composition of the loan portfolio, the effect of changes in the local real estate market on collateral values, trends in past dues, the experience of the lender, changes in lending policy, the effects on the loan portfolio of current economic indicators and their probable impact on borrowers, 56 historical loan loss experience, the amount of nonperforming loans and related collateral and the evaluation of the Company’s loan portfolio by the loan review function. The Company may assign a specific allowance to individual loans based on an impairment analysis. Loans are considered impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The amount of impairment is based on an analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the estimated market value or the fair value of the underlying collateral. Loans evaluated for impairment include all commercial, real estate, agricultural loans and TDRs. The Company follows a loan review program to evaluate the credit risk in the loan portfolio. Throughout the loan review process, the Company maintains an internally classified loan watch list, which, along with a delinquency list of loans, helps management assess the overall quality of the Company’s loan portfolio and the adequacy of the allowance for loan losses. Charge-offs occur when the Company deems a loan to be uncollectible. Analysis of the Allowance for Loan Losses. The following table sets forth the allowance for loan losses by category of loan: (dollars in thousands) Amount 2017 2016 2015 2014 2013 % of Total Loans(1) % of Total Loans(1) % of Total Loans(1) Amount Amount % of Total Loans(1) % of Total Loans(1) Amount Amount As of December 31, Commercial loans Real estate: Commercial real estate, construction, land and land development Residential real estate Single family interim construction Agricultural Consumer Other Unallocated $ 10,599 16.3% $ 8,593 13.7% $ 10,573 18.3% $ 5,051 21.0% $ 2,401 14.0% 23,301 3,447 1,583 250 205 (32) 49 63.2 14.3 4.4 1.3 0.5 — — 18,399 2,760 1,301 207 242 29 60 65.3 14.1 5.1 1.2 0.6 — — 13,007 2,339 769 215 164 8 (32) 59.2 15.5 4.7 1.3 1.0 — — 10,110 2,205 669 246 146 — 125 55.7 16.2 4.3 1.2 1.6 — — 7,872 2,440 577 238 365 2 65 56.4 19.8 4.8 2.3 2.7 — — Total allowance for loan losses $ 39,402 100.0% $ 31,591 100.0% $ 27,043 100.0% $ 18,552 100.0% $ 13,960 100.0% (1) Represents the percentage of Independent’s total loans included in each loan category. As of December 31, 2017, the allowance for loan losses amounted to $39.4 million, or 0.62%, of total loans held for investment, compared with $31.6 million, or 0.69%, as of December 31, 2016 and $27.0 million, or 0.68%, as of December 31, 2015. The dollar increase during 2017 is 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 year reflects loans acquired in the Carlile transaction that were recorded at fair value without an allowance at acquisition date. The increase in the allowance during 2016 was primarily due to an increase in general reserves for organic growth and for risks within our energy portfolio during the first half of the year, primarily related to lower oil prices. Higher charge-offs during the period offset the overall increase and mostly relate to charge-offs of energy loans. The allowance for loan losses as a percentage of nonperforming loans increased from 177.06% at December 31, 2016, to 255.62% at December 31, 2017, due to an increase in the recorded allowance balance as well as a reduction in total nonperforming loans. As of December 31, 2017, the Company had made a specific allowance for loan losses of $3.8 million for impaired loans totaling $15.2 million, compared with a specific allowance of $185 thousand for impaired loans totaling $17.9 million as of December 31, 2016. The increase in specific reserves was due primarily to the addition of $3 million in specific reserves placed on a commercial impaired loan credit relationship which was added to the impaired loan listing in 2016. The decrease in impaired loans during 2017 was mainly due to the pay-off of two commercial real estate loans totaling $5.8 million offset by the addition of a commercial construction loan and a commercial loan totaling $3.7 million. The allowance for loan losses as a percentage of nonperforming loans decreased slightly from 181.99% at December 31, 2015, to 177.06% at December 31, 2016, due to a combination of increases in both the allowance and nonperforming loan balances. As of December 31, 2016, the Company had made a specific allowance for loan losses of $185 thousand for impaired loans totaling $17.9 million, compared with a specific allowance of $3.2 million for impaired loans totaling $15.5 million as of December 31, 2015. This decrease in specific reserves was due primarily to charge-offs on energy loans during the year as discussed above. 57 Although the allowance for loan losses to nonperforming loans has increased significantly over the periods presented in the Company’s consolidated financial statements appearing in this Annual Report on Form 10-K, the Company does not expect to decrease the Company’s allowance as a percentage of total loans. The allowance is primarily related to loans evaluated collectively and will continue to increase as the Company’s loan portfolio grows. Additional provision expense will vary depending on future credit quality trends within the portfolio. The following table provides an analysis of the provisions for loan losses, net charge-offs and recoveries for the years ended December 31, 2017, 2016, 2015, 2014 and 2013 and the effects of those items on the Company’s allowance for loan losses: (dollars in thousands) As of and for the Year Ended December 31, 2017 2016 2015 2014 2013 Allowance for loan losses-balance at beginning of year $ 31,591 $ 27,043 $ 18,552 $ 13,960 $ 11,478 Charge-offs Commercial Real estate: Commercial real estate, construction, land and land development Residential real estate Single-family interim construction Consumer Other Total charge-offs Recoveries Commercial Real estate: Commercial real estate, construction, land and land development Residential real estate Single-family interim construction Consumer Other Total recoveries Net charge-offs Provision for loan losses (81) (4,384) (606) (368) (612) (15) — (134) (182) (190) (602) 28 31 4 — 46 39 148 (54) (401) — (27) (104) (4,970) (69) (9) — (52) (124) (860) (371) (32) — (63) (80) (634) (130) — (10) (54) (914) (1,440) 13 10 12 — 8 35 78 28 19 20 42 5 — 14 31 120 79 8 11 6 24 147 28 10 — 17 25 100 (454) 8,265 (4,892) 9,440 (740) 9,231 (767) 5,359 (1,340) 3,822 Allowance for loan losses-balance at end of year $ 39,402 $ 31,591 $ 27,043 $ 18,552 $ 13,960 Ratios Net charge-offs to average loans outstanding 0.01% 0.12% 0.02% 0.03% 0.09% Allowance for loan losses to nonperforming loans at end of year Allowance for loan losses to total loans at end of year (1) 255.62 0.62 177.06 0.69 181.99 0.68 183.43 0.58 152.39 0.81 (1) Calculation excludes loans held for sale and mortgage warehouse purchase loans from total loans. The Company’s ratio of allowance to loan losses to total loans as of December 31, 2017 was 0.62%, down slightly from 0.69% at December 31, 2016. The decrease in the allowance for loan losses as a percentage of loans from prior year reflects that loans acquired in the Carlile transaction were recorded at fair value without an allowance at acquisition date. The ratio of net charge- offs to average loans outstanding during the year ended December 31, 2017 decreased to 0.01% from 0.12% for the year ended December 31, 2016. The increase in charge-offs during 2016 was primarily related to energy-related charge-offs. The Company’s ratio of allowance to loan losses to total loans as of December 31, 2016 was 0.69%, up slightly from 0.68% at December 31, 2015. The slight increase is due to provisions for organic growth during the period. Due to the stabilization of oil prices during the second half of 2016 and reductions in the energy portfolio, no additional provisions for the energy portfolio were necessary during the second half of the year. The ratio of net charge-offs to average loans outstanding during the year ended December 31, 2016 increased to 0.12% from 0.02% for the year ended December 31, 2015. The increase in charge- offs during 2016 is primarily related to energy-related charge-offs, which were mostly reserved at December 31, 2015. 58 Securities Available for Sale The Company’s investment strategy aims to maximize earnings while maintaining liquidity in securities with minimal credit, interest rate and duration risk. The types and maturities of securities purchased are primarily based on the Company’s current and projected liquidity and interest rate sensitivity positions. The following table sets forth the book value, which is equal to fair market value because all investment securities the Company held were classified as available for sale as of the applicable date, and the percentage of each category of securities as of December 31, 2017, 2016 and 2015: (dollars in thousands) Securities available for sale U.S. Treasury securities Government agency securities Obligations of state and municipal subdivisions Residential pass-through securities Other securities Total securities available for sale As of December 31, 2017 2016 2015 Book Value % of Total Book Value % of Total Book Value % of Total $ 37,154 211,509 229,613 274,377 10,349 $ 763,002 4.9% $ 27.7 30.1 35.9 1.4 3,147 122,267 87,256 103,765 — 100.0% $ 316,435 1.0% $ 38.6 27.6 32.8 — 1,002 135,300 85,416 51,745 — 100.0% $ 273,463 0.4% 49.5 31.2 18.9 — 100.0% The Company recognized gains on the sale of securities of $124 thousand, $4 thousand and $134 thousand for the years ended December 31, 2017, 2016 and 2015, respectively. Securities represented 8.8%, 5.4% and 5.4% of the Company’s total assets at December 31, 2017, 2016 and 2015, respectively. Certain investment securities are valued at less than their historical cost. Management evaluates securities for other-than- temporary impairment (OTTI) on at least a quarterly basis and more frequently when economic of market conditions warrant such an evaluation. Management does not intend to sell any debt securities it holds and believes the Company more likely than not will not be required to sell any debt securities it holds before their anticipated recovery, at which time the Company will receive full value for the securities. Management has the ability and intent to hold the securities classified as available for sale that were in a loss position as of December 31, 2017 for a period of time sufficient for an entire recovery of the cost basis of the securities. For those securities that are impaired, the unrealized losses are largely due to interest rate changes. The fair value is expected to recover as the securities approach their maturity date. Management believes any impairment in the Company’s securities at December 31, 2017, is temporary and no impairment has been realized in the Company’s consolidated financial statements. 59 The following table sets forth the book value, scheduled maturities and weighted average yields for the Company’s investment portfolio as of December 31, 2017: (dollars in thousands) U.S. Treasury securities Maturing within one year Maturing in one to five years Maturing in five to ten years Maturing after ten years Total U.S. Treasury securities Government agency securities Maturing within one year Maturing in one to five years Maturing in five to ten years Maturing after ten years Total government agency securities Obligations of state and municipal subdivisions Maturing within one year Maturing in one to five years Maturing in five to ten years Maturing after ten years Total obligations of state and municipal subdivisions Residential pass through securities Maturing within one year Maturing in one to five years Maturing in five to ten years Maturing after ten years Total residential pass through securities Other securities Maturing within one year Maturing in one to five years Maturing in five to ten years Maturing after ten years Total other securities Total investment securities Book Value % of Total Investment Securities Weighted Average Yield $ $ $ 16,968 15,129 5,057 — 37,154 52,246 130,709 28,554 — 211,509 18,882 54,009 52,290 104,432 229,613 301 214,246 56,161 3,669 274,377 10,349 — — — 10,349 763,002 2.1% 1.02% 2.0 0.7 — 4.8 6.8% 17.1 3.7 — 27.6 2.5 7.1 6.9 13.7 30.2 — 28.1 7.4 0.5 36.0 1.4 — — — 1.4 100.0% 1.58 2.03 — 1.38 1.07 1.68 2.43 — 1.64 1.48 1.88 2.33 2.70 2.32 2.77 2.28 3.56 2.84 2.55 2.23 — — — 2.23 2.16% 60 The following table summarizes the amortized cost of securities classified as available for sale and their approximate fair values as of the dates shown: (dollars in thousands) Securities available for sale As of December 31, 2017 U.S. treasuries Government agency securities Obligations of state and municipal subdivisions Residential pass through securities guaranteed by FNMA, GNMA, FHLMC, FHR, and GNR Other securities As of December 31, 2016 U.S. treasuries Government agency securities Obligations of state and municipal subdivisions Residential pass through securities guaranteed by FNMA, GNMA and FHLMC As of December 31, 2015 U.S. treasuries Government agency securities Obligations of state and municipal subdivisions Residential pass through securities guaranteed by FNMA, GNMA, FHLMC and FHR Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value $ 37,480 $ — $ (326) $ 213,649 228,782 274,356 10,397 764,664 3,208 123,605 88,358 103,869 319,040 999 135,630 83,442 50,640 $ $ $ $ $ $ $ $ 37,154 211,509 229,613 274,377 10,349 3,147 122,267 87,256 103,765 83 2,118 1,229 — (2,223) (1,287) (1,208) (48) 3,430 $ (5,092) $ 763,002 — $ (61) $ (1,479) (2,022) (1,032) 141 920 928 1,989 3 237 2,222 1,202 $ $ (4,594) $ 316,435 — $ (567) (248) (97) 1,002 135,300 85,416 51,745 $ 270,711 $ 3,664 $ (912) $ 273,463 The Company’s available for sale securities, carried at fair value, increased $446.6 million, or 141.1%, during 2017 and increased $43.0 million, or 15.7% during 2016. The increase in 2017 was due to securities acquired in the Carlile acquisition. The increase in 2016 is due to excess liquidity attributed to organic asset growth in addition to maintaining the portfolio at targeted percent of total assets. Residential pass-through securities (mortgage backed securities) are securities that have been developed by pooling a number of real estate mortgages that are principally issued by federal agencies. These securities are deemed to have high credit ratings, and minimum regular monthly cash flows of principal and interest are guaranteed by the issuing agencies. Unlike U.S. Treasury and U.S. government agency securities, which have a lump sum payment at maturity, mortgage-backed securities provide cash flows from regular principal and interest payments and principal prepayments throughout the lives of the securities. Premiums and discounts on mortgage-backed securities are amortized over the expected life of the security and may be impacted by prepayments. As such, mortgage-backed securities which are purchased at a premium will generally suffer decreasing net yields as interest rates drop because home owners tend to refinance their mortgages resulting in prepayments and an acceleration of premium amortization, Securities purchased at a discount will generally obtain higher net yields in a decreasing interest rate environment as prepayments result in acceleration of discount accretion. Cash and Cash Equivalents Cash and cash equivalents decreased by $73.9 million, or 14.6% to $431.1 million at December 31, 2017 from $505.0 million at December 31, 2016. Cash and cash equivalents increased by $211.7 million, or 72.2% to $505.0 million at December 31, 2016 from $293.3 million at December 31, 2015. Cash and cash equivalent balances can vary due to cash needs and volatility of several large title company and commercial accounts. Certificates of Deposit Held in Other Banks The Company owned certificates of deposit held in other banks in the amount of $13.0 million and $2.7 million as of December 31, 2017 and 2016, respectively. The increase in certificates held at December 31, 2017 is a result of certificates acquired in the Carlile acquisition and certificates purchased in the first quarter of 2017 due to excess liquidity. The Company owned certificates of deposit held in other banks in the amount of $2.7 million and $61.7 million as of December 31, 2016 and 2015, respectively. All of the certificates held at December 31, 2015 were acquired in the Grand Bank transaction in November 2015. 61 Goodwill and Core Deposit Intangible, Net Goodwill represents the excess of the consideration paid over the fair value of the net assets acquired. The Company’s total goodwill was $621.5 million at December 31, 2017, $258.3 million as of December 31, 2016 and $258.6 million as of December 31, 2015. The increase in the goodwill balance from December 31, 2016 to December 31, 2017 is a result of $363.1 million in goodwill recognized from the acquisition of Carlile. The slight decrease in the goodwill balance from December 31, 2015 to December 31, 2016 was due to small measurement period adjustments related to the Grand Bank acquisition. Liabilities Total liabilities increased $2.2 billion, or 41.8%, to $7.3 billion as of December 31, 2017, from $5.2 billion as of December 31, 2016, primarily due to $1.8 billion in deposit accounts acquired in the Carlile transaction in addition to organic deposit growth, increases of $69.9 million in FHLB advances, $29.6 million in other borrowings (subordinated debentures) and $9.4 million in junior subordinated debt acquired in the Carlile acquisition, respectively. Total liabilities increased $752.7 million, or 17.0%, to $5.2 billion as of December 31, 2016, from $4.4 billion as of December 31, 2015, primarily due to organic deposit growth and increases of $172.4 million in FHLB advances and $45.0 million in other borrowings (subordinated debentures), respectively. Deposits Deposits represent Independent Bank’s primary source of funds. The Company continues to focus on growing core deposits through the Company’s relationship driven banking philosophy and community-focused marketing programs. Total deposits increased $2.1 billion, or 44.9%, to $6.6 billion as of December 31, 2017 from $4.6 billion as of December 31, 2016. The increase is primarily due to $1.8 billion in deposit accounts acquired in the Carlile transaction in addition to organic growth. Brokered deposits totaled $400.1 million and $497.4 million at December 31, 2017 and 2016, respectively. As of December 31, 2017 and 2016, noninterest-bearing demand, interest-bearing checking, savings deposits and limited access money market accounts accounted for 86.5% and 81.3%, respectively, of the Company’s total deposits, while individual retirement accounts and certificates of deposit made up 13.5% and 18.7%, respectively, of total deposits. Noninterest-bearing demand deposits totaled $1.9 billion, or 28.7% of total deposits, as of December 31, 2017, compared with $1.1 billion, or 24.4% of total deposits, as of December 31, 2016. The total cost of deposits increased eight basis points from 0.38% at December 31, 2016 to 0.46% at December 31, 2017. The average cost of interest-bearing deposits was 0.63% per annum for 2017 compared with 0.51% for 2016. The increase in cost of funds was primarily due to higher rates offered on public fund certificates of deposit and money market accounts due to competition in our markets but also due to increased interest rates on deposit products tied to Fed Funds rates and short-term FHLB advances. Total deposits increased $548.8 million, or 13.6%, to $4.6 billion as of December 31, 2016 from $4.0 billion as of December 31, 2015. The increase was due to organic deposit growth as well as an increase in use of brokered funds. Brokered deposits totaled $497.4 million and $476.6 million at December 31, 2016 and 2015, respectively. As of December 31, 2016 and 2015, noninterest-bearing demand, interest-bearing checking, savings deposits and limited access money market accounts accounted for 81.3% and 79.0%, respectively, of the Company’s total deposits, while individual retirement accounts and certificates of deposit made up 18.7% and 21.0%, respectively, of total deposits. Noninterest-bearing demand deposits totaled $1.1 billion, or 24.4% of total deposits, as of December 31, 2016, compared with $1.1 billion, or 26.6% of total deposits, as of December 31, 2015. The total cost of deposits increased four basis points from 0.34% at December 31, 2015 to 0.38% at December 31, 2016. The average cost of interest-bearing deposits was 0.51% per annum for 2016 compared with 0.46% for 2015. The increase in cost of funds was primarily due to increased rates on public fund accounts. 62 The following table summarizes the Company’s average deposit balances and weighted average rates for the periods presented: (dollars in thousands) Deposit Type Noninterest-bearing demand accounts Interest-bearing checking accounts Savings accounts Limited access money market accounts Certificates of deposit, including individual retirement accounts (IRA) Total deposits For the Year Ended December 31, 2017 For the Year Ended December 31, 2016 For the Year Ended December 31, 2015 Weighted Average Rate Weighted Average Rate Weighted Average Rate Balance Balance Balance $ 1,671,872 —% $1,076,340 —% $ 895,789 —% 2,630,477 263,381 605,064 1,002,753 0.51 0.14 1.02 0.86 1,761,509 150,223 429,647 830,964 0.44 0.17 0.44 0.74 1,297,948 143,476 319,982 842,087 0.44 0.18 0.26 0.63 $ 6,173,547 0.46% $4,248,683 0.38% $3,499,282 0.34% The following table sets forth the maturity of time deposits (including IRA deposits) of $100,000 or more as of December 31, 2017: (dollars in thousands) Individual retirement accounts Certificates of deposit (excluding CDARS) CDARS Total Short-Term Borrowings Maturity within: Three Months Three to Six Months Six to Twelve Months After Twelve Months Total $ $ 2,376 $ 5,255 $ 8,517 $ 7,795 $ 23,943 138,978 54,681 119,750 15,205 209,657 10,787 147,566 965 615,951 81,638 196,035 $ 140,210 $ 228,961 $ 156,326 $ 721,532 The Company’s deposits have historically provided the Company with a major source of funds to meet the daily liquidity needs of the Company’s customers and fund growth in earning assets. However, from time to time the Company may also engage in short-term borrowings. At December 31, 2017, 2016 and 2015, the Company had $100.0 million, $0.0 million and $70.0 million, respectively, in short-term borrowings outstanding, all of which were short-term FHLB advances. These were recorded on the balance sheet under FHLB advances and are included in the total advances outstanding as discussed in the section below. The Company has not historically needed to engage in significant short-term borrowing through sources such as federal funds purchased, securities sold under agreements to repurchase or Federal Reserve Discount Window advances to meet the daily liquidity needs of the Company’s customers or fund growth in earning assets. 63 FHLB Advances In addition to deposits, the Company utilizes FHLB advances either as a short-term funding source or a longer-term funding source and to manage the Company’s interest rate risk on the Company’s loan portfolio. FHLB advances can be particularly attractive as a longer-term funding source to balance interest rate sensitivity and reduce interest rate risk. The Company’s FHLB borrowings totaled $530.7 million as of December 31, 2017, compared with $460.7 million as of December 31, 2016, and $288.3 million as of December 31, 2015. The increase for FHLB borrowings during 2017 is primarily to manage liquidity needs. The increase for FHLB borrowings during 2016 is primarily to manage liquidity needs related to the Grand acquisition, primarily due to volatility from the title company accounts and increased wire volume as well as organic loan growth. As of December 31, 2017, 2016 and 2015, the Company had $1.7 billion, $830.8 million and $817.0 million, respectively, in unused and available advances from the FHLB. At December 31, 2017, the Company’s FHLB advances are collateralized by assets, including a blanket pledge of certain loans with a carrying value of $3.0 billion and FHLB stock. As of December 31, 2017, 2016 and 2015, the Company had $741.5 million, $691.7 million and $461.5 million, respectively, in undisbursed advance commitments (letters of credit) with the FHLB. The FHLB letters of credit were obtained in lieu of pledging securities to secure public fund deposits that are over the FDIC insurance limit. There were no disbursements against the advance commitments as of December 31, 2017, 2016 or 2015. The following table provides a summary of the Company’s FHLB advances at the dates indicated: Fixed-rate, fixed term, at rates from 1.02% to 5.57%, with a weighted-average of 1.43% (maturing January 2018 through January 2026) 530,667 — Fixed-rate, fixed term, at rates from 0.46% to 5.57%, with a weighted-average of 0.98% (maturing October 2017 through January 2026) $ — $ 460,746 — — Fixed-rate, fixed term, at rates from 0.31% to 6.26%, with a weighted-average of 1.21% (maturing January 2016 through January 2026) — $ — $ 288,325 As of December 31, 2017, the scheduled maturities of the Company’s FHLB advances were as follows (dollars in thousands): As of December 31, 2017 2016 2015 Maturing Within First Year Second Year Third Year Fourth Year Fifth Year Thereafter Principal Amount to Mature As of December 31, 2017 $ $ 440,000 65,020 — 25,000 — 647 530,667 Other Long-Term Indebtedness As of December 31, 2017, 2016 and 2015, the Company had $136.9 million, $107.3 million and $70.8 million, respectively, of long-term indebtedness (other than FHLB advances and junior subordinated debentures) outstanding, which included subordinated debentures. The increase from December 31, 2016 to December 31, 2017 was mainly due to a new issuance of $30 million in 5.0% fixed and floating rate subordinated debentures. The increase from December 31, 2015 to December 31, 2016 was due to the issuance of $45.0 million in the Company's subordinated notes offset by the repayments totaling $5.8 million of other subordinated debentures. As of December 31, 2017, the Company’s long-term gross indebtedness of $110 million and $30 million will mature on August 1, 2024 and December 31, 2027, respectively, with an optional redemption at December 31, 2022 for the newly issued debt. Junior Subordinated Debentures As of December 31, 2017, 2016 and 2015, the Company had outstanding an aggregate of $31.6 million, $18.1 million and $18.1 million, respectively, principal amount of seven series of junior subordinated securities issued to seven unconsolidated 64 subsidiary trusts. Each series of debentures was purchased by one of the trusts with the net proceeds of the issuance by such trust of floating rate trust preferred securities. These junior subordinated debentures are unsecured and will mature between March 2033 and September 2037. Each of the series of debentures bears interest at a per annum rate equal to three-month LIBOR plus a spread that ranges from 3.26% to 4.70%, with a weighted average spread of 3.76%. As of December 31, 2017, the interest rate on the various series of debentures was 4.63%, 4.21%, 3.85%, 4.70%, 3.19%, 3.26% and 3.26%, respectively, while as of December 31, 2016, the interest rate on the various series of debentures was 4.14%, 3.73%, 3.32%, 4.17% and 2.56%, respectively. Interest on each series of these debentures is payable quarterly, although the Company may, from time to time defer the payment of interest on any series of these debentures. A deferral of interest payments would, however, restrict the Company’s right to declare and pay cash distributions, including dividends on the Company’s common stock, or making distributions with respect to any of the Company’s future debt instruments that rank equally or are junior to such debentures. The Company may redeem the debentures, which are intended to qualify as Tier 1 capital, at the Company’s option, subject to approval of the Federal Reserve. Capital Resources and Liquidity Management Capital Resources The Company’s stockholders’ equity is influenced by the Company’s earnings, the sales and redemptions of common stock that the Company makes, stock based compensation expense, the dividends the Company pays on its common stock, and, to a lesser extent, any changes in unrealized holding gains or losses occurring with respect to the Company’s securities available for sale. Total stockholder’s equity was $1.3 billion at December 31, 2017, compared with $672.4 million at December 31, 2016, an increase of approximately $663.7 million. The increase was due primarily to the issuance of common stock, net of offering costs, totaling $565.2 million in connection with the Company's acquisition of Carlile acquisition. In additional, net income earned for the year totaling $76.5 million and the issuance of common stock, net of offering costs, totaling $26.8 million, stock awards amortization of $4.7 million and an increase in the unrealized gain (loss) on securities totaling $613 thousand offset by dividends paid of $10.2 million. Total stockholder’s equity was $672.4 million at December 31, 2016, compared with $603.4 million at December 31, 2015, an increase of approximately $69.0 million. The increase was due primarily to the net income earned for the year totaling $53.5 million and the issuance of common stock, net of offering costs totaling $19.9 million. In addition, there was stock awards amortization of $5.4 million offset by dividends paid of $6.3 million and a decrease in the unrealized gain (loss) on securities totaling $3.5 million. Liquidity Management Liquidity refers to the measure of the Company’s ability to meet the cash flow requirements of depositors and borrowers, while at the same time meeting the Company’s operating, capital and strategic cash flow needs, all at a reasonable cost. The Company’s asset and liability management policy is intended to maintain adequate liquidity and, therefore, enhance the Company’s ability to raise funds to support asset growth, meet deposit withdrawals and lending needs, maintain reserve requirements, and otherwise sustain operations. The Company accomplishes this through management of the maturities of the Company’s interest-earning assets and interest-bearing liabilities. The Company believes that the Company’s present position is adequate to meet the Company’s current and future liquidity needs. The Company continuously monitors the Company’s liquidity position to ensure that assets and liabilities are managed in a manner that will meet all of the Company’s short-term and long-term cash requirements. The Company manages the Company’s liquidity position to meet the daily cash flow needs of customers, while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of the Company’s shareholders. The Company also monitors its liquidity requirements in light of interest rate trends, changes in the economy, and the scheduled maturity and interest rate sensitivity of the investment and loan portfolios and deposits. Liquidity risk management is an important element in the Company’s asset/liability management process. The Company’s short-term and long-term liquidity requirements are primarily to fund on-going operations, including payment of interest on deposits and debt, extensions of credit to borrowers, capital expenditures and shareholder dividends. These liquidity requirements are met primarily through cash flow from operations, redeployment of pre-paid and maturing balances in the Company’s loan and investment portfolios, debt financing and increases in customer deposits. The Company’s liquidity position is supported by management of liquid assets and liabilities and access to alternative sources of funds. Liquid assets 65 include cash, interest-bearing deposits in banks, federal funds sold, securities available for sale and maturing or prepaying balances in the Company’s investment and loan portfolios. Liquid liabilities include core deposits, federal funds purchased, securities sold under repurchase agreements and other borrowings. Other sources of liquidity include the sale of loans, the ability to acquire additional national market noncore deposits, the issuance of additional collateralized borrowings such as FHLB advances, the issuance of debt securities, borrowings through the Federal Reserve’s discount window and the issuance of equity securities. For additional information regarding the Company’s operating, investing and financing cash flows, see the Consolidated Statements of Cash Flows provided in the Company’s consolidated financial statements. In addition to the liquidity provided by the sources described above, the Company maintains correspondent relationships with other banks in order to sell loans or purchase overnight funds should additional liquidity be needed. As of December 31, 2017, 2016 and 2015 the Company had established federal funds lines of credit with nine unaffiliated banks totaling $225 million, $225 million and $200 million, respectively. Based on the values of stock, securities, and loans pledged as collateral, as of December 31, 2017, 2016 and 2015, the Company had additional borrowing capacity with the FHLB of $1.7 billion, $830.8 million and $817.0 million, respectively. The Company also maintains a secured line of credit with the Federal Reserve Bank with an availability to borrow approximately $552.2 million and $384.2 million at December 31, 2017 and 2016, respectively. Approximately $740.6 million and $515.2 million of commercial loans were pledged as collateral at December 31, 2017 and 2016, respectively. There were no borrowings against this line as of December 31, 2017 or 2016. The Company also participates in an exchange that provides direct overnight borrowings with other financial institutions. The funds are provided on an unsecured basis. Borrowing availability totaled $60 million and $75 million at December 31, 2017 and 2016, respectively. There were no borrowings as of December 31, 2017 and 2016. The Company has a $50 million unsecured revolving line of credit with an unrelated commercial bank. The line bears interest at LIBOR plus 2.50% and matures October 19, 2018. As of December 31, 2017 and 2016, there was no outstanding balance on the line. The Company is required to meet certain financial covenants on a quarterly basis, which includes maintaining $5.0 million in cash at Independent Bank Group and meeting minimum capital ratios. The Company is a corporation separate and apart from Independent Bank and, therefore, the Company must provide for the Company’s own liquidity. The Company’s main source of funding is dividends declared and paid to the Company by Independent Bank. Statutory and regulatory limitations exist that affect the ability of Independent Bank to pay dividends to the Company. Management believes that these limitations will not impact the Company’s ability to meet the Company’s ongoing short-term cash obligations. For additional information regarding dividend restrictions, see “Risk Factors-Risks Related to the Company’s Business” in Part I, Item 1A, and “Supervision and Regulation” under Part I, Item 1, “Business.” Regulatory Capital Requirements The Company’s capital management consists of providing equity to support the Company’s current and future operations. The Company is subject to various regulatory capital requirements administered by state and federal banking agencies, including the TDB, Federal Reserve and the FDIC. Failure to meet minimum capital requirements may prompt certain actions by regulators that, if undertaken, could have a direct material adverse effect on the Company’s financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The Basel III Capital Rules became effective for the Company on January 1, 2015. Starting in January 2016, the implementation of the capital conservation buffer became effective for the Company starting at the 0.625% level and increasing 0.625% each year thereafter, until it reaches 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company's ability to make capital distributions, including dividend payments and stock repurchases and to pay discretionary bonuses to executive officers. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in regulatory capital. Accordingly, amounts reported as accumulated other comprehensive income/loss related to securities available for sale do not increase or reduce regulatory capital and are not included in the calculation of risk-based capital and leverage ratios. Regulatory agencies for banks and bank holding companies utilize capital guidelines designed to measure capital and take into consideration the risk inherent in both on-balance sheet and 66 off-balance sheet items. Please refer to Note 19 - Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report. The FDIC has promulgated regulations setting the levels at which an insured institution such as Independent Bank would be considered well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. Independent Bank is considered well-capitalized for purposes of the applicable prompt corrective action regulations. As of December 31, 2017, 2016 and 2015, the Company and Bank exceeded all capital ratio requirements under prompt corrective action and other regulatory requirements, as detailed in the table below: As of December 31, 2017 Tier 1 capital to average assets ratio Common equity tier 1 to risk-weighted assets ratio Tier 1 capital to risk-weighted assets ratio Total capital to risk-weighted assets ratio 8.92% 10.30% 4.00-5.00% 9.61 10.05 12.56 11.59 11.59 12.15 4.50-6.50 6.00-8.00 8.00-10.00 Ratio ≥5.00% ≥6.50 ≥8.00 ≥10.00 Actual Consolidated Ratio Actual Bank Ratio Required to be considered adequately capitalized Required to be considered well capitalized (Bank only) Ratio As of December 31, 2016 Actual Consolidated Ratio 7.82% 8.20 8.55 11.38 Actual Bank Ratio 9.65% 10.55 10.55 11.19 Required to be considered adequately capitalized Required to be considered well capitalized (Bank only) Ratio 4.00-5.00% 4.50-6.50 6.00-8.00 8.00-10.00 Ratio ≥5.00% ≥6.50 ≥8.00 ≥10.00 As of December 31, 2015 Actual Consolidated Ratio 8.28% 7.94 8.92 11.14 Actual Bank Ratio 9.72% 10.43 10.43 11.06 Required to be considered adequately capitalized Required to be considered well capitalized (Bank only) Ratio 4.00-5.00% 4.50-6.50 6.00-8.00 8.00-10.00 Ratio ≥5.00% ≥6.50 ≥8.00 ≥10.00 Tier 1 capital to average assets ratio Common equity tier 1 to risk-weighted assets ratio Tier 1 capital to risk-weighted assets ratio Total capital to risk-weighted assets ratio Tier 1 capital to average assets ratio Common equity tier 1 to risk-weighted assets ratio Tier 1 capital to risk-weighted assets ratio Total capital to risk-weighted assets ratio Contractual Obligations In the ordinary course of the Company’s operations, the Company enters into certain contractual obligations, such as obligations for operating leases and other arrangements with respect to deposit liabilities, FHLB advances and other borrowed funds. The Company believes that it will be able to meet its contractual obligations as they come due through the maintenance of adequate cash levels. The Company expects to maintain adequate cash levels through profitability, loan and securities repayment and maturity activity and continued deposit gathering activities. The Company has in place various borrowing mechanisms for both short-term and long-term liquidity needs. As noted earlier, the Company issued $30.0 million in subordinated debentures during 2017. Other than these subordinated debentures and normal changes in the ordinary course of business, there have been no significant changes in the types of contractual obligations or amounts due since December 31, 2016. 67 The following table contains supplemental information regarding the Company’s total contractual obligations as of December 31, 2017: (dollars in thousands) Deposits without a stated maturity Time deposits FHLB advances Subordinated debt Junior subordinated debentures Operating leases Total contractual obligations Payments Due Within One Year One to Three Years Three to Five Years After Five Years Total $ 5,738,423 $ — $ — $ — $ 5,738,423 695,608 440,000 — — 2,794 160,451 65,020 — — 38,340 25,000 — — 4,429 3,304 — 647 136,911 27,654 4,707 894,399 530,667 136,911 27,654 15,234 $ 6,876,825 $ 229,900 $ 66,644 $ 169,919 $ 7,343,288 The Company believes that it will be able to meet its contractual obligations as they come due through the maintenance of adequate cash levels. The Company expects to maintain adequate cash levels through profitability, loan and securities repayment and maturity activity and continued deposit gathering activities. The Company has in place various borrowing mechanisms for both short-term and long-term liquidity needs. Corporate Headquarters Contract. On January 18, 2018, the Company entered into an agreement with an independent contractor for the oversight and construction of the Company's new corporate headquarters office building in McKinney, Texas. The 165,000 square foot building is estimated to cost approximately $50 million and expected to be completed in early 2019. Off-Balance Sheet Arrangements In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States, are not included in the Company’s consolidated balance sheets. However, the Company has only limited off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on the Company’s financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources. Independent Bank enters into these transactions to meet the financing needs of the Company’s customers. These transactions include commitments to extend credit and issue standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. Commitments to Extend Credit. Independent Bank enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of Independent Bank’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Independent Bank minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. Standby Letters of Credit. Standby letters of credit are written conditional commitments that Independent Bank issues to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, Independent Bank would be required to fund the commitment. The maximum potential amount of future payments Independent Bank could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the customer is obligated to reimburse Independent Bank for the amount paid under this standby letter of credit. Commitments to extend credit were $1.3 billion, $865.7 million and $838.3 million, as of December 31, 2017, 2016 and 2015, respectively. Outstanding standby letters of credit were $10.5 million, $10.6 million and $10.4 million, as of December 31, 2017, 2016 and 2015, respectively. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements. The Company manages the Company’s liquidity in light of the aggregate amounts of commitments to extend credit and outstanding standby letters of credit in effect from time to time to ensure that the Company will have adequate sources of liquidity to fund such commitments and honor drafts under such letters of credit. The Company guarantees the distributions and payments for redemption or liquidation of the trust preferred securities issued by the Company’s wholly owned subsidiary trusts to the extent of funds held by the trusts. Although this guarantee is not separately recorded, the obligation underlying the guarantee is fully reflected on the Company’s consolidated balance sheets as 68 junior subordinated debentures, which debentures are held by the Company’s subsidiary trusts. The junior subordinated debentures currently qualify as Tier 1 capital under the Federal Reserve capital adequacy guidelines. For additional information regarding the subordinated debentures, see Note 12 to the Company’s consolidated financial statements. Asset/Liability Management and Interest Rate Risk The principal objective of the Company’s asset and liability management function is to evaluate the interest rate risk within the balance sheet and pursue a controlled assumption of interest rate risk while maximizing net income and preserving adequate levels of liquidity and capital. The Investment Committee of Independent Bank’s board of directors has oversight of Independent Bank’s asset and liability management function, which is managed by the Company’s Treasurer. The Treasurer meets with the Company’s Chief Financial Officer and senior executive team regularly to review, among other things, the sensitivity of the Company’s assets and liabilities to market interest rate changes, local and national market conditions and market interest rates. That group also reviews the liquidity, capital, deposit mix, loan mix and investment positions of the Company. The Company’s management and the board of directors are responsible for managing interest rate risk and employing risk management policies that monitor and limit the Company’s exposure to interest rate risk. Interest rate risk is measured using net interest income simulations and market value of portfolio equity analyses. These analyses use various assumptions, including the nature and timing of interest rate changes, yield curve shape, prepayments on loans, securities and deposits, deposit decay rates, pricing decisions on loans and deposits, reinvestment/ replacement of asset and liability cash flows. Instantaneous parallel rate shift scenarios are modeled and utilized to evaluate risk and establish exposure limits for acceptable changes in net interest margin. These scenarios, known as rate shocks, simulate an instantaneous change in interest rates and use various assumptions, including, but not limited to, prepayments on loans and securities, deposit decay rates, pricing decisions on loans and deposits, reinvestment and replacement of asset and liability cash flows. The Company also analyzes the economic value of equity as a secondary measure of interest rate risk. This is a complementary measure to net interest income where the calculated value is the result of the market value of assets less the market value of liabilities. The economic value of equity is a longer term view of interest rate risk because it measures the present value of the future cash flows. The impact of changes in interest rates on this calculation is analyzed for the risk to the Company’s future earnings and is used in conjunction with the analyses on net interest income. The Company conducts periodic analyses of our sensitivity to interest rate risks through the use of a third-party proprietary interest-rate sensitivity model. That model has been customized to our specifications. The analyses conducted by use of that model are based on current information regarding our actual interest-earnings assets, interest-bearing liabilities, capital and other financial information that we supply. The third party uses that information in the model to estimate our sensitivity to interest rate risk. The Company’s interest rate risk model indicated that it was in a balanced rate sensitive position in terms of interest rate sensitivity as of December 31, 2017. The table below illustrates the impact of an immediate and sustained 200 and 100 basis point increase and a 100 basis point decrease in interest rates on net interest income based on the interest rate risk model as of December 31, 2017: Hypothetical Shift in Interest Rates (in bps) % Change in Projected Net Interest Income 200 100 (100) (0.44)% (0.17) 1.42 These are good faith estimates and assume that the composition of the Company’s interest sensitive assets and liabilities existing at each year-end will remain constant over the relevant twelve-month measurement period and that changes in market interest rates are instantaneous and sustained across the yield curve regardless of duration of pricing characteristics of specific assets or liabilities. Also, this analysis does not contemplate any actions that the Company might undertake in response to changes in market interest rates. The Company believes these estimates are not necessarily indicative of what actually could occur in the event of immediate interest rate increases or decreases of this magnitude. As interest-bearing assets and liabilities re-price in different time frames and proportions to market interest rate movements, various assumptions must be made based on historical relationships of these variables in reaching any conclusion. Since these correlations are based on competitive and 69 market conditions, the Company anticipates that its future results will likely be different from the foregoing estimates, and such differences could be material. Many assumptions are used to calculate the impact of interest rate fluctuations. Actual results may be significantly different than the Company’s projections due to several factors, including the timing and frequency of rate changes, market conditions and the shape of the yield curve. The computations of interest rate risk shown above do not include actions that the Company’s management may undertake to manage the risks in response to anticipated changes in interest rates and actual results may also differ due to any actions taken in response to the changing rates. As part of the Company’s asset/liability management strategy, the Company’s management has emphasized the origination of shorter duration loans as well as variable rate loans to limit the negative exposure to a rate increase, as well as obtaining funding with FHLB advances to manage interest rate risks on funding of loan commitments. Additionally, a significant portion of the loans in the Company’s loan portfolio typically have short-term maturities. The Company’s strategy with respect to liabilities has been to emphasize transaction accounts, particularly noninterest or low interest-bearing nonmaturing deposit accounts, which are less sensitive to changes in interest rates. In response to this strategy, nonmaturing deposit accounts have been a large portion of total deposits and totaled 86.5%, 81.3% and 79.0% of total deposits as of December 31, 2017, 2016 and 2015, respectively. The Company had brokered deposits, including CDARS totaling $400.1 million, $497.4 million and $476.6 million, at December 31, 2017, 2016 and 2015, respectively. The Company intends to focus on the Company’s strategy of increasing noninterest or low interest-bearing nonmaturing deposit accounts, but may consider the use brokered deposits as a stable source of lower cost funding. Inflation and Changing Prices The largest component of earnings for the Company is net interest income, which is affected by changes in interest rates. Changes in interest rates are also influenced by changes in the rate of inflation, although not necessarily at the same rate or in the same magnitude. In management's opinion, changes in interest rates have a more significant impact to the Company's operations than do changes in inflation. However, inflation, does impact the operating costs of the Company, primarily employment costs and other services. Critical Accounting Policies and Estimates The preparation of the Company’s consolidated financial statements in accordance with U.S. generally accepted accounting principles, or GAAP, requires the Company to make estimates and judgments that affect the Company’s reported amounts of assets, liabilities, income and expenses and related disclosure of contingent assets and liabilities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under current circumstances, results of which form the basis for making judgments about the carrying value of certain assets and liabilities that are not readily available from other sources. The Company evaluates the Company’s estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions. Accounting policies, as described in detail in the notes to the Company’s consolidated financial statements are an integral part of the Company’s financial statements. A thorough understanding of these accounting policies is essential when reviewing the Company’s reported results of operations and the Company’s financial position. The Company believes that the critical accounting policies and estimates discussed below require the Company to make difficult, subjective or complex judgments about matters that are inherently uncertain. Changes in these estimates, that are likely to occur from period to period, or the use of different estimates that the Company could have reasonably used in the current period, would have a material impact on the Company’s financial position, results of operations or liquidity. Acquired Loans. The Company’s accounting policies require that the Company evaluates all acquired loans for evidence of deterioration in credit quality since origination and to evaluate whether it is probable that the Company will collect all contractually required payments from the borrower. Acquired loans from the transactions accounted for as a business combination include both nonperforming loans with evidence of credit deterioration since their origination date and performing loans. The Company accounts for performing loans under ASC Paragraph 310-20, Nonrefundable Fees and Other Costs, with the related difference in the initial fair value and unpaid principal balance (the discount) recognized as interest income on a level yield basis over the life of the loan. The Company accounts for the nonperforming loans acquired in accordance with ASC Paragraph 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. At the date of the acquisition, acquired loans are recorded at their fair value. 70 The Company recognizes the difference between the undiscounted cash flows the Company expects (at the time the Company acquires the loan) to be collected and the investment in the loan, or the “accretable yield,” as interest income using the interest method over the life of the loan. The Company does not recognize contractually required payments for interest and principal that exceed undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” as a yield adjustment, loss accrual or valuation allowance. Increases in the expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over the loan’s remaining life, while decreases in expected cash flows are recognized as impairment. Valuation allowances on these impaired loans reflect only losses incurred after the acquisition. Upon an acquisition, the Company generally continues to use the classification of acquired loans classified nonaccrual or 90 days and accruing. The Company does not classify acquired loans as TDRs unless the Company modifies an acquired loan subsequent to acquisition that meets the TDR criteria. Reported delinquency of the Company’s purchased loan portfolio is based upon the contractual terms of the loans. Allowance for Loan Losses. The allowance for loan losses represents management’s estimate of probable and reasonably estimable credit losses inherent in the loan portfolio. In determining the allowance, the Company estimates losses on individual impaired loans, or groups of loans which are not impaired, where the probable loss can be identified and reasonably estimated. On a quarterly basis, the Company assesses the risk inherent in the Company’s loan portfolio based on qualitative and quantitative trends in the portfolio, including the internal risk classification of loans, historical loss rates, changes in the nature and volume of the loan portfolio, industry or borrower concentrations, delinquency trends, detailed reviews of significant loans with identified weaknesses and the impacts of local, regional and national economic factors on the quality of the loan portfolio. Based on this analysis, the Company records a provision for loan losses in order to maintain the allowance at appropriate levels. Determining the amount of the allowance is considered a critical accounting estimate, as it requires significant judgment and the use of subjective measurements, including management’s assessment of overall portfolio quality. The Company maintains the allowance at an amount the Company believes is sufficient to provide for estimated losses inherent in the Company’s loan portfolio at each balance sheet date, and fluctuations in the provision for loan losses may result from management’s assessment of the adequacy of the allowance. Changes in these estimates and assumptions are possible and may have a material impact on the Company’s allowance, and therefore the Company’s financial position, liquidity or results of operations. Goodwill and Core Deposit Intangible. The excess purchase price over the fair value of net assets from acquisitions, or goodwill, is evaluated for impairment at least annually and on an interim basis if an event or circumstance indicates that it is likely an impairment has occurred. The Company first assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing a two step impairment test is unnecessary. If the Company concludes otherwise, then it is required to perform a first step of the two step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit. In testing for impairment in the past, the fair value of net assets is estimated based on an analysis of the Company’s market value. Determining the fair value of goodwill is considered a critical accounting estimate because the allocation of the fair value of goodwill to assets and liabilities requires significant management judgment and the use of subjective measurements. Variability in the market and changes in assumptions or subjective measurements used to allocate fair value are reasonably possible and may have a material impact on the Company’s financial position, liquidity or results of operations. Core deposit intangibles are acquired customer relationships that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Core deposit intangibles are being amortized on a straight-line basis over their estimated useful lives of ten years. Core deposit intangibles are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Recently Issued Accounting Pronouncements The Company has evaluated new accounting pronouncements that have recently been issued and have determined that there are no new accounting pronouncements that should be described in this section that will materially impact the Company’s operations, financial condition or liquidity in future periods. Refer to Note 2 of the Company’s audited consolidated financial statements for a discussion of recent accounting pronouncements that have been adopted by the Company or that will require enhanced disclosures in the Company’s financial statements in future periods. 71 ITEM 7A.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Evaluation of disclosure controls and procedures. As of the end of the period covered by this Annual Report on Form 10-K, the Company carried out an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management was required to apply judgment in evaluating its disclosure controls and procedures. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective as of the end of the period covered by this report. Management’s report on internal control over financial reporting. The management, including the Chief Executive Officer and Chief Financial Officer, of the Company is responsible for establishing and maintaining an effective system of internal control over financial reporting. The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act. As of December 31, 2017, management, including the Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in “Internal Control-Integrated Framework,” issued by the Committee of Sponsoring Organizations, or COSO, of the Treadway Commission (2013 framework). Based on the assessment, management determined that the Company maintained effective internal control over financial reporting, as of December 31, 2017, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with U.S. generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2017, and our report dated February 27, 2018 expressed an unqualified opinion. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ RSM US LLP Dallas, Texas February 27, 2018 73 ITEM 9B.

Board Composition The Company’s board of directors currently has twelve (12) members serving on the board. The number of directors may be changed only by resolution of the board of directors within the range set forth in the Company’s certificate of formation (unless the Company’s shareholders act to amend the authorized number of directors designated in the Company’s certificate of formation). The board of directors may increase the number of directors by two and fill these vacancies until the next annual meeting of shareholders. As discussed in greater detail below, the board of directors has affirmatively determined that ten of its twelve current directors qualify as independent directors under Rule 5605(a)(2) of the Nasdaq Stock Market Rules and the regulations of the SEC. Classification of the Company’s Directors In accordance with the terms of the Company’s amended and restated certificate of formation, the Company’s current board of directors is divided into three classes, Class I, Class II and Class III, with each class serving staggered three-year terms as follows: • • • The Class I directors are Daniel W. Brooks, Craig E. Holmes, Tom C. Nichols, and G. Stacy Smith, and their terms will expire at the annual meeting of shareholders to be held in 2020; The Class II directors are William E. Fair, Mark K. Gormley, Donald L. Poarch and Michael T. Viola, and their terms will expire at the annual meeting of shareholders to be held in 2018; and The Class III directors are David R. Brooks, Douglas A. Cifu, Christopher M. Doody, and J. Webb Jennings, III, and their terms will expire at the annual meeting of shareholders to be held in 2019. Board Leadership Structure David R. Brooks currently serves as the Company’s Chairman of the Board, Chief Executive Officer and President. Mr. Brooks has served in both of these positions since the inception of the Company in 2002. Mr. Brooks’ primary duties are to lead the Company’s board of directors in establishing the Company’s overall vision and strategic plan and to lead the Company’s management in carrying out that plan. While the Company recognizes the inherent conflict of interest that arises when the positions are held by one person, the Company believes that the overall benefit of Mr. Brooks’ leadership in both 79 roles outweighs any potential disadvantage of this structure. The Company’s lead independent director is Douglas A. Cifu who has served in this role since 2013. As lead independent director, Mr. Cifu serves as a liaison between the Chairman and the independent directors, presides over executive sessions of the independent directors, and consults with the Chairman on major corporate decisions. The Company has also structured its management team to mitigate the corporate governance risk related to the dual positions held by David R. Brooks. Daniel W. Brooks, the Company’s Vice Chairman and Chief Risk Officer, is responsible for overseeing the Company’s credit function, the most important component of the Company’s operations. By having other executive officers with separate and distinct roles, the Company believes that it will obtain benefits similar to the benefits of having a separate Chairman and Chief Executive Officer. Board Committees In February 2013, the Company’s board of directors established standing committees at the Company level in connection with the discharge of its responsibilities. These committees include a Compensation Committee, a Corporate Governance and Nominating Committee, an Audit Committee and a Strategic Planning Committee. In the future, the Company’s board of directors also may establish such additional committees as it deems appropriate, in accordance with applicable law and regulations and the Company’s certificate of formation and Bylaws. Compensation Committee. The members of the Company’s Compensation Committee are William E. Fair (Chairman), G. Stacy Smith and J. Webb Jennings, III. The Company’s board of directors has evaluated the independence of each of the members of the Compensation Committee and has affirmatively determined that each meets the definition of an “independent director” under Nasdaq Global Select Market rules. The Board has determined that each of the members of the Compensation Committee qualifies as a “nonemployee director” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, or the Exchange Act, and an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended. None of the directors who served on the Compensation Committee at any time during fiscal 2017 were officers or employees of the Company or were former officers or employees of the Company. Further, none of the directors who served on the Compensation Committee at any time during fiscal 2017 has any relationship with the Company requiring disclosure under “Certain Relationships and Related Transactions and Director Independence” under Item 13 below, other than William E. Fair, as described in that section. Finally, no executive officer of the Company serves, or in the past fiscal year has served, as a member of the compensation committee (or other board committee performing equivalent functions) of any entity that has one or more of its executive officers serving on the Company’s Compensation Committee. In accordance with its charter, the Compensation Committee has the responsibility and authority of establishing the philosophy that underlies the Company’s executive compensation program, for establishing and implementing that program and for reviewing and setting the compensation of each of the Company’s named executive officers and other executive officers. The Company’s board of directors has directed the Compensation Committee, in accordance with its charter, to ensure that the Company’s executive compensation program is designed and executed in a manner necessary to reflect the Company’s executive compensation philosophy, to achieve the Company’s goals and objectives and is consistent with regulatory requirements. Specifically, the Compensation Committee has responsibility for, among other things: • • • Reviewing, monitoring and approving the Company’s overall compensation structure, policies and programs (including benefit plans) and assessing whether the compensation structure establishes appropriate incentives for the Company’s executive officers and other employees and meets the Company’s corporate objectives; Determining the annual compensation of the Company’s named executive officers as noted in “Executive Compensation and Other Matters”; Reviewing the Company’s executive officer compensation program and determining if: • Such program is appropriately linked to the Company’s short-term and long-term financial and other performance; The interests of the Company’s executive officers are appropriately aligned with the interests of the Company’s shareholders or can be more appropriately aligned through greater equity ownership by the Company’s executive officers and by having a greater proportion of executive officer compensation tied to the Company’s financial and other performance; and • 80 • The base salaries and incentive compensation opportunities provided to the Company’s executive officers are competitive with those packages offered by other similarly situated and similarly performing financial institutions; • • • • Addressing such other matters relating to the Company’s executive compensation program as it deems appropriate; Reviewing the compensation decisions made by the Company’s named executive officers with respect to the Company’s other executive officers; Overseeing the administration of the Company’s equity plans and other incentive compensation plans and programs and preparing recommendations and periodic reports to the Company’s board of directors relating to these matters; and Handling such other matters that are specifically delegated to the Compensation Committee by the Company’s board of directors from time to time. The Company’s Compensation Committee has adopted a written charter, which sets forth the committee’s duties and responsibilities. The charter of the Compensation Committee is available on the Company’s website at www.ibtx.com. From time to time, the Compensation Committee may, by resolution of the Compensation Committee, delegate to one or more other committees of the board of directors of the Company separate but concurrent authority, to the extent specified in such resolution, to administer such plans with respect to employees of the Company and its subsidiaries and consultants who are not subject to the short-swing profit restrictions of Section 16(b) of the Exchange Act. Since 2013, the Compensation Committee has engaged Johnson Associates, Inc. (“Johnson Associates”) as an independent compensation consultant. Johnson Associates has and continues to advise the Compensation Committee on a variety of matters regarding executive compensation, including compensation levels, incentive awards and plans, and performance awards and plans, and conducts analyses and performance measures when requested by the Compensation Committee. Other than its engagement through the Compensation Committee, Johnson Associates does not perform and has never performed any other services for the Company. At the recommendation of the Compensation Committee, the Company’s board of directors adopted the 2015 Performance Award Plan, which was approved by the Company’s shareholders at the Company’s 2015 annual meeting. Pursuant to the 2015 Performance Award Plan, executive officers are eligible to receive cash and equity based performance awards based upon the achievement of goals related to the performance of the Company. At the end of each year, the Compensation Committee reviews the level of achievement of the pre-established performance goals. For 2017, the Company granted target awards based upon pre-tax net income. The 2017 awards are intended to qualify as deductible “performance based” compensation for federal income tax purposes. Corporate Governance and Nominating Committee. The members of the Company’s Corporate Governance and Nominating Committee are Douglas A. Cifu (Chairman), Christopher M. Doody, Donald L. Poarch and Michael T. Viola. The Company’s board of directors has evaluated the independence of each of the members of the Corporate Governance and Nominating Committee and has affirmatively determined that each meets the definition of an “independent director” under Nasdaq Global Select Market rules and SEC regulations. The Company’s Corporate Governance and Nominating Committee has responsibility for, among other things: • recommending persons to be selected by the Company’s board of directors as nominees for election as directors and to fill any vacancies on the Company’s board of directors; provided that if this Committee is not comprised solely of independent directors under the Nasdaq Global Select Market rules, the Committee shall make its recommendations to the independent members of the Company’s board of directors, who, in turn, shall nominate persons to be selected by the Company’s board of directors as nominees for election as directors and to fill any vacancies on the Company’s board of directors; • monitoring the function of the Company’s standing committees and recommending any changes, including the • • • • creation or elimination of any committee; developing, reviewing and monitoring compliance with the Company’s corporate governance guidelines; reviewing and approving all related person transactions for potential conflicts of interest situations on an ongoing basis; reviewing annually the composition of the Company’s board of directors as a whole and making recommendations; and handling such other matters that are specifically delegated to the Corporate Governance and Nominating Committee by the Company’s board of directors from time to time. 81 The Company’s Corporate Governance and Nominating Committee has adopted a written charter, which sets forth the committee’s duties and responsibilities. The charter of the Corporate Governance and Nominating Committee is available on the Company’s website at www.ibtx.com. In carrying out its functions, the Corporate Governance and Nominating Committee has developed the following qualification criteria for all potential nominees for election, including incumbent directors, board nominees and shareholder nominees: • • • • • • integrity and high ethical standards in the nominee’s professional life; sufficient educational and professional experience, business experience or comparable service on other boards of directors to qualify the nominee for service on the Company’s board of directors; evidence of leadership and sound judgment in the nominee’s professional life; whether the nominee is well recognized in the community and has a demonstrated record of service to the community; a willingness to abide by any published code of conduct or ethics for the Company; and a willingness and ability to devote sufficient time to carrying out the duties and responsibilities required as a member of the Company’s board of directors. The Corporate Governance and Nominating Committee evaluates potential nominees for the Company’s board of directors to determine if they have any conflicts of interest that may interfere with their ability to serve as effective board members and determines whether they are “independent” in accordance with Nasdaq Global Select Market rules and SEC regulations (to ensure that, at all times, at least a majority of the Company’s directors are independent). Although the Company does not have a separate diversity policy, the committee considers the diversity of the Company’s directors and nominees in terms of knowledge, experience, skills, expertise and other demographics that may contribute to the board of directors. Prior to nominating or, if applicable, recommending to the independent members of the Company’s board of directors, an existing director for re-election to the board of directors, the Corporate Governance and Nominating Committee will consider and review the following attributes with respect to each existing director: • • • • • attendance and performance at meetings of the Company’s board of directors and the committees on which such director serves; length of service on the Company’s board of directors; experience, skills and contributions that the existing director brings to the Company’s board of directors; independence and any conflicts of interest; and any significant change in the director’s status, including the attributes considered for initial membership on the Company’s board of directors. Director Nominations. The Company’s board of directors does not have a policy with respect to the consideration of any director candidates recommended by shareholders. All recommended candidates will be considered by the Corporate Governance and Nominating Committee of the board of directors for nomination in light of the attributes specified in this section. A notice of a shareholder to make a nomination of a person for election as a director of the Company must be made in writing and received by the Corporate Secretary of the Company (i) in the event of an annual meeting of shareholders, not more than one hundred twenty (120) days and not less than ninety (90) days in advance of the anniversary date of the immediately preceding annual meeting; provided, however, that in the event that the annual meeting is called on a date that is not within thirty (30) days before or after such anniversary date, notice by the shareholder in order to be timely must be so received not later than the close of business on the fifteenth (15 ) day following the day on which notice of the date of the annual meeting was mailed or public disclosure of the date of the annual meeting was made, whichever first occurs; or (ii) in the event of a special meeting of shareholders, such notice shall be received by the Corporate Secretary not later than the close of business on the fifteenth (15 ) day following the day on which notice of the meeting is first mailed to shareholders or public disclosure of the date of the special meeting was made, whichever first occurs. Every such notice by a shareholder must set forth: (i) the name and residence address of the shareholder of the Company who intends to make a nomination or bring up any other matter; 82 (ii) a representation that the shareholder is a holder of the Company’s voting stock (indicating the class and number of shares owned) and intends to appear in person or by proxy at the meeting to make the nomination or bring up the matter specified in the notice; (iii) with respect to notice of an intent to make a nomination for the election of a person as a director of the Company, a description of all arrangements or understandings among the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the shareholder; and (iv) with respect to an intent to make a nomination, such other information regarding each nominee proposed by such shareholder as would have been required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission had each nominee been nominated by the board of directors of the Company. At the meeting of shareholders, the Chairman shall declare out of order and disregard any nomination or other matter not presented in accordance with these requirements. The shareholder must also submit the nominee’s consent to be elected and to serve. The board of directors may require any nominee to furnish any other information that may be needed to determine the eligibility and qualifications of the nominee. Any recommendations in proper form received from shareholders will be evaluated in the same manner that potential nominees recommended by directors or management are evaluated. Director Nominee Agreements. In connection with the Company’s acquisition of Carlile, effective April 1, 2017, the Company entered into nominee agreements with Tom C. Nichols, Trident IV PF Depositary Holdings, LLC and Trident IV Depositary Holdings, LLC (together, these entities, “Trident”) and LEP Carlile Holdings, LLC (“LEP”) whereby Mr. Nichols, Trident and LEP would have certain continuing rights to propose nominees to the Company’s board of directors and maintain certain representation on the board. Under his agreement, Mr. Nichols has certain continuing rights to be a board nominee to the Company’s board of directors. Under his agreement and provided that Mr. Nichols continues to satisfy the Company’s governance and ethics policies, the Company is required to nominate and recommend Mr. Nichols for election as a Class I director of the Company, and the Company, as the sole shareholder of Independent Bank, is required to elect Mr. Nichols as a director of Independent Bank. If Mr. Nichols no longer beneficially owns at least 50% of the aggregate number of shares of common stock of the Company that he received in the Company’s acquisition of Carlile, then upon the written request of the Company’s board, Mr. Nichols will resign from the Company’s board and the Company will have no further obligations to nominate and recommend Mr. Nichols for election to the Company’s board. Under the agreements with Trident and LEP, those investors each have the right to designate one person as a nominee to serve on the Company’s board during the term of their agreements. Mr. Doody is currently the designee of Trident, and Mr. Gormley is currently the designee of LEP. Provided that these individuals continue to satisfy the Company’s governance and ethics policies, the Company is obligated to nominate and recommend Mr. Gormley as a Class II director and Mr. Doody as a Class III director. Trident and LEP have the right to appoint substitute representatives in certain circumstances. If either Trident or LEP no longer beneficially own at least 50% of the aggregate number of shares of the Company common stock that they received in the Company’s acquisition of Carlile, then upon the written request of the Company’s board, such investor will cause their nominee to resign from the Company’s board and the Company will have no further obligation to nominate and recommend such investor’s nominee for election to the Company’s board. As of the date of this proxy statement, Trident and LEP each beneficially own more than 5% of the outstanding common stock of the Company. The board is currently comprised of twelve directors, and Messrs. Nichols, Doody and Gormley, as the three former Carlile related nominees, constitute 25% of the Company’s board members. Each of Messrs. Nichols, Doody and Gormley will receive the same compensation and indemnification as the Company’s other nonemployee directors. Audit Committee. The members of the Company’s Audit Committee are Craig E. Holmes (Chairman), Mark K. Gormley and G. Stacy Smith. The Company’s board of directors has evaluated the independence of each of the members of the Audit Committee and has affirmatively determined that (i) each of the members meets the definition of an “independent director” under Nasdaq Global Select Market rules, (ii) each of the members satisfies the additional independence standards under applicable SEC rules for audit committee service and (iii) each of the members has the ability to read and understand fundamental financial statements. In addition, the board of directors has determined that Mr. Holmes also qualifies as a financial expert and has the required financial sophistication due to his experience and background, which Nasdaq Global Select Market rules require at least one such Audit Committee member have. 83 The Company’s Audit Committee has responsibility for, among other things: • selecting and reviewing the performance of the Company’s independent auditors and approving, in advance, all engagements and fee arrangements; reviewing the independence of the Company’s independent auditors; • • reviewing actions by management on recommendations of the independent auditors and internal auditors; • meeting with management, the internal auditors and the independent auditors to review the effectiveness of the • • • Company’s system of internal controls and internal audit procedures; reviewing the Company’s earnings releases and reports filed with the SEC; reviewing reports of bank regulatory agencies and monitoring management’s compliance with recommendations contained in those reports; and handling such other matters that are specifically delegated to the Audit Committee by the Company’s board of directors from time to time. The Company’s Audit Committee has adopted a written charter, which sets forth the committee’s duties and responsibilities. The charter of the Audit Committee is available on the Company’s website at www.ibtx.com. Strategic Planning Committee. The members of the Strategic Planning Committee are G. Stacy Smith (Chairman), David R. Brooks, William E. Fair, and Tom C. Nichols. The Company’s board of directors has evaluated the independence of each of the members of the Strategic Planning Committee and has affirmatively determined that Mr. Nichols, Mr. Smith and Mr. Fair meet the definition of an “independent director” under the Nasdaq stock market rules. Mr. Brooks does not meet the definition of “independent director” under the Nasdaq Global Select Market rules because he is an executive officer of the Company. The Company’s Strategic Planning Committee has responsibility for, among other things: • • • • • establishing plans for the growth of the Company, including organic growth plans and strategic acquisitions; identifying new market areas; identifying new management candidates to enhance product and geographic expansion; identifying acquisition targets and developing plans to pursue acquisitions of such identified targets; and reviewing capital and financing levels, financial partners, and ensuring continued access to capital and financing. The Company’s Strategic Planning Committee has adopted a written charter, which sets forth the committee’s duties and responsibilities. The charter of the Strategic Planning Committee is available on the Company’s website at www.ibtx.com. Code of Conduct; Code of Ethics for Chief Executive Officer and Senior Financial Officers The Company has a Code of Conduct in place that applies to all of the Company’s directors, officers and employees. The Code of Conduct sets forth the standard of conduct that the Company expects all of the Company’s directors, officers and employees to follow, including the Company’s Chief Executive Officer and Chief Financial Officer. In addition, the Company has a Code of Ethics for the Chief Executive Officer and Senior Financial Officers that applies to each of the Company’s senior executive and senior financial officers, including the Company’s Chief Executive Officer and Chief Financial Officer, principal accounting officer and controller, and sets forth specific standards of conduct and ethics that the Company expects from such individuals in addition to those set forth in the Code of Conduct.

EXECUTIVE COMPENSATION The individuals who served as the Company’s Chief Executive Officer and Chief Financial Officer during 2017, as well as the Company’s four other most highly compensated executive officers for 2017, are collectively referred to as the Company’s “named executive officers.” EXECUTIVE COMPENSATION Compensation Discussion and Analysis Overview of Compensation Program The Compensation Committee of the Board is responsible for making recommendations to the Board relating to the compensation of the Company’s Chairman of the Board, Chief Executive Officer and President, the other named executive officers, and the directors. William E. Fair, J. Webb Jennings, III, and G. Stacy Smith, each of whom the Board has determined to be an independent director, as defined in the Nasdaq Global Select Market rules and SEC regulations, serve on the Compensation Committee. This discussion and analysis describes the components of the Company’s compensation program for its named executive officers and describes the basis on which the Compensation Committee made its 2017 compensation determinations with respect to the named executive officers of the Company. Role of Executives in Establishing Compensation The Compensation Committee, either as a committee or together with the other independent directors of the Company, make all recommendations to the Board with respect to the compensation of the Company’s executive officers, including the named executive officers, which the Board then reviews and, if satisfactory, approves. The Chairman of the Board, Chief Executive Officer and President provides input regarding the performance of the other named executive officers and makes recommendations for compensation amounts payable to the other named executive officers. The Compensation Committee evaluates the Chairman of the Board, Chief Executive Officer and President’s performance in light of the Company’s goals and objectives relevant to his compensation. The Chairman of the Board, Chief Executive Officer and President is not involved with any aspect of determining his own pay. Compensation Committee Activity When reviewing named executive officer compensation, the Compensation Committee and the Board review all elements of current and historic compensation for each named executive officer. The Compensation Committee also makes recommendations to the Board as to all stock grants to the named executive officers made pursuant to the Company’s equity incentive plans. Objectives/Philosophy The Company has compensated the Company’s named executive officers through a mix of base salary, cash incentive bonuses, restricted stock grants and other benefits, including to a limited extent, perquisites. The Company believes the current mix of these compensation elements and the amounts of each element provide the Company’s named executive officers with compensation that is reasonable, competitive within the Company’s markets, appropriately reflects the Company’s performance and their particular contributions to that performance, and takes into account applicable regulatory guidelines and requirements. Each of the Company’s named executive officers is also an officer of Independent Bank and has substantial responsibilities in connection with the day-to-day operations of Independent Bank. As a result, each named executive officer devotes a substantial majority of his or her business time to the operations of Independent Bank, and the compensation he or she receives is paid largely to compensate that named executive officer for his or her services to Independent Bank. The Compensation Committee’s philosophy is to provide a compensation package that attracts and retains executive talent, provides rewards for superior performance and produces consequences for underperformance. It is also the Compensation Committee’s practice to provide a balanced mix of cash and equity-based compensation that the committee believes appropriate to mitigate risk and align the short and long-term interests of the Company’s executives with that of the Company’s shareholders and to encourage executives to participate and perform as equity owners of the Company. 86 We believe that to attract and retain the quality of executive talent necessary to achieve our long-term strategic business goals, we must offer a competitive compensation package to our executives. The Compensation Committee seeks to attract executive talent by offering competitive base salaries, annual performance incentive opportunities, and long-term awards under the Company’s long-term incentive programs (including restricted stock grants under our equity incentive plan). When considering pay decisions for our named executive officers, we generally target a range of the median to the 75th percentile of the market for total compensation. While applying no specific formula or weighting of each factor, we also consider the executive’s scope of responsibilities, skills and experience, overall Company performance and the Board of Directors’ evaluation of the executive’s individual performance. Based on our business strategy and the results we expect from our executives, we attempt to blend their compensation pay between short and long-term pay as well as the mix of cash and equity compensation. We believe the design of our compensation programs and the amounts paid have been and continue to be appropriate and reasonable. We continually review our programs to ensure they are aligned with our business objectives and shareholder interests. The Compensation Committee measures the Company’s senior management compensation levels with comparable compensation levels in industry benchmark studies and peer group data. We use survey data to benchmark our executive positions to those at other banking institutions with total asset size similar to ours. In each of the last four years, the Compensation Committee engaged Johnson Associates to conduct an independent third party executive compensation review and provide analyses, conclusions and recommended considerations for the key executives of the Company. The review included an analysis of the total direct compensation (base salary, annual incentives, long-term incentives and perquisites), plus an assessment of the competitiveness of the Company’s incentive compensation, based on asset size, geography and operations, as compared to a peer group of companies and published survey data from similarly sized companies in the banking industry. The peer group companies considered by the Compensation Committee were as follows: Texas Capital Bancshares Sterling Bancorp Home Bancshares Bank of the Ozarks First Financial Bankshares LegacyTexas (Viewpoint) Eagle Bancorp Pinnacle Financial Partners CVB Financial Bancfirst S&T Bancorp Opus Bank Simmons First National Corp Community Bank System South State Bank Florida Community Bank It is the Compensation Committee’s practice to provide incentives that promote both the short and long-term financial objectives of the Company. To motivate our executives to achieve our strategic business goals, we offer the opportunity to earn the targeted level of pay through incentive compensation that correlates to the Company’s short and long-term performance. These incentives are based on financial and investment metrics underlying Company performance, including net income, loan and deposit growth, credit quality, return on equity and tangible book value. Annual bonuses reward achievement of short-term objectives based on the Company’s operational business plan that are established to encourage our executives to make decisions currently that promote shareholder value. Long-term incentive programs encourage executives to focus on the Company’s long-term strategic goals, which are catalysts to drive shareholder value, while accomplishing a high rate of retention of our executives. Our compensation program also accounts for individual performance, which enables the Compensation Committee to differentiate among executives and emphasize the link between personal performance and compensation. Compensation Policies and Practices and the Company’s Risk Management The Compensation Committee and the Board have reviewed the compensation policies and practices for all employees and does not believe that any risks arise from the Company’s compensation policies and practices for the Company’s executive officers and other employees that are reasonably likely to have a material adverse effect on the Company’s operations, results of operations or financial condition. Elements of Compensation The following is a summary of the elements of compensation provided to our Chief Executive Officer and other members of senior management. Further details and disclosures of each of these elements can be found in the tabular disclosures that follow. 87 Base Salary. Base salaries paid to our executives are intended to competitively compensate them for the experience and skills needed to perform their current roles, as well as reward their prior individual performance. We seek to provide our senior management with a level of assured cash compensation in the form of base salary that reflects their professional status, accomplishments and experience. The base salaries of the Company’s named executive officers are reviewed annually by the Compensation Committee as part of the Company’s performance review process as well as upon the promotion of an executive officer to a new position or another change in job responsibility. In establishing base salaries for the Company’s named executive officers for 2017 and prospectively for 2018, the Compensation Committee, relied on external market data obtained from outside sources, including Johnson Associates, the Compensation Committee’s compensation consultant, and the Independent Bankers Association of Texas and other banking industry trade groups. In addition to considering the information obtained from such sources, the Compensation Committee, has considered: • • • • • each named executive officer’s scope of responsibility; each named executive officer’s years of experience; the types and amount of the elements of compensation to be paid to each named executive officer; the Company’s financial performance and performance with respect to other aspects of the Company’s operations, such as the Company’s growth, asset quality, profitability and other matters, including the status of the Company’s relationship with the banking regulatory agencies; and each named executive officer’s individual performance and contributions to the Company’s performance, including leadership, team work and community service. As part of this process, the Compensation Committee reviews the Johnson Associates peer group analysis and identifies the market median base salary. The Compensation Committee then reviews the Company’s financial performance, comparing performance metrics of the Company described above to the same performance metrics of the peer group companies. The Compensation Committee significantly weighs the extent to which the Company out performs or under performs the peer group companies in its review of named executive officer compensation. Following its review, the Compensation Committee makes recommendations to the Company’s board of directors, which reviews the recommendation and sets the annual salaries for the named executive officers. The Compensation Committee met in December 2017 and approved base salaries for 2018 for the named executives as follows: Mr. David R. Brooks-$725,000; Ms. Michelle S. Hickox-$325,000; Mr. Daniel W. Brooks-$425,000; Mr. Brian Hobart-$400,000; and Mr. James. C. White-$310,000. Annual Incentive Bonus. The Company typically has paid a cash bonus and made grants of restricted shares of Company common stock under the Company’s 2013 Equity Incentive Plan, or Equity Incentive Plan, to its named executive officers. The Compensation Committee uses annual incentive cash and stock awards to recognize and reward those named executive officers who contribute meaningfully to the Company’s performance for the year. The Compensation Committee has, within its sole discretion, determined whether such cash bonuses will be paid for any year and the amount of any bonus paid as well as determined whether stock awards will be granted for any year and the number of any restricted shares granted and the vesting of such awards. In determining whether to pay annual cash bonuses and make stock awards, the Compensation Committee establishes performance goals for the Company and the executive officer at the beginning of the year and then reviews the Company’s and the executive’s performance at the end of the year to determine the extent to which the pre- established goals have been obtained. Performance measures used by the Compensation Committee in establishing performance goals have included such factors as: • • • • • • the overall financial soundness of the Company (asset quality, risk controls, balance sheet/capital management); the Company’s organic loan growth and growth through strategic acquisitions; the Company’s profitability (earnings growth and operating efficiencies); the executive’s role in the Company’s achievement of target percentage increases in growth and profitability; the executive’s role in specific strategic and operational functions, such as successful implementation of the Company’s acquisition strategy, overall management of financial reporting, and supervision of the Company’s credit function; and the personal performance of the executive officer and contributions to the Company’s performance for the year, including leadership, team work and community service. The Compensation Committee also reviews external market data in weighting achievement of performance goals and applies market medians to the level of performance in setting the cash and stock awards. The Compensation Committee also 88 establishes performance measures and sets applicable performance targets for each performance measure with respect to performance-based cash incentive and equity incentive awards under the 2015 Performance Award Plan. Specifically, the goals for executive officers were based upon the Company’s overall performance in executing the Company’s key strategic initiatives, which are organic growth, growth through acquisitions, increased profitability and improved efficiency, maintenance of excellent credit quality and enhancement of shareholder value. The successful execution of these strategies are measured by organic loan and deposit growth, completion of strategic acquisitions, net income, efficiency ratios, asset quality and regulatory capital ratios, earnings per share, return on equity, tangible book value, and the payment of a dividend. Mr. David Brooks’ goals for 2017 were based upon all of these metrics. Mr. Dan Brooks’ goals for 2017 were weighted toward asset quality metrics (nonperforming assets to total assets ratio, nonperforming loans to total loans ratio and charge offs as a percentage of total loans). Mr. Hobart’s goals for 2017 were weighted toward organic loan growth and maintaining appropriate diversification of the overall loan portfolio (commercial real estate, commercial and industrial, etc.). Ms. Hickox’s goals for 2017 were weighted toward earnings performance (net income, net interest margin and efficiency ratio). Mr. White’s goals for 2017 were weighted toward operating efficiency metrics. For 2017, the maximum award of cash and stock for senior management of the Company was 200% of the executive’s base salary. In 2017, the metrics set for the named executive officers were those believed to be generally controllable by the respective named executive officer and which the Compensation Committee believed would result in increased shareholder value if achieved. Based on the achievement of the performance criteria in 2017, Mr. David Brooks earned 200% of his base salary, Ms. Hickox earned 100% of her base salary, Mr. Daniel Brooks earned 125% of his base salary, Mr. Hobart earned 121.33% of his base salary, and Mr. White earned 96.49% of his base salary. While the performance goals drive the bonus plan and executive awards, the Compensation Committee retains discretion to adjust payouts of the awards based on the performance of the Company, including audit regulatory compliance and community service and the individual officer performance, as deemed appropriate. The Compensation Committee met in December 2017 to establish the specific goals for the named executive’s 2018 bonus. Such goals were based on similar criteria as established in 2017. We presently offer restricted stock grants under the Equity Incentive Plan approved by shareholders in 2013. The purpose of our Equity Incentive Plan is to attract, motivate, retain and reward high quality executives and other employees, officers, directors, consultants and other persons who provide services to the Company or its related entities by enabling such persons to acquire or increase an ownership interest in the Company in order to strengthen the mutuality of interests between such persons and the Company’s shareholders, and providing such persons with long term performance incentives to expend their maximum efforts in the creation of shareholder value. We continue to review this program to ensure that this form of equity compensation will drive our executives toward successful long-term business results. Grants made under the Equity Incentive Plan typically vest over a three or five year period, commencing on the first anniversary of the grant.Unvested restricted stock granted under the Equity Incentive Plan vest immediately upon the occurrence of a change of control event. Unvested awards granted under the Equity Incentive Plan expire should the officer be terminated with cause, as defined in the Equity Incentive Plan. Restricted stock grants awarded under the Equity Incentive Plan are not assignable or transferable by a grantee. Generally, the Compensation Committee, based in part on discussions with the Company’s Chairman of the Board, Chief Executive Officer and President, determines the amount of restricted stock awards that are part of the annual incentive bonuses. In January, 2018, the Company granted key employees, including the named executive officers disclosed herein, an aggregate of 90,462 shares of restricted stock, which vest over three years (38,962 shares) and five years (51,500 shares). Restricted stock grants are also made from time to time in connection with the employment or retention of officers. These restricted stock grants typically vest over five years and are based upon market conditions, past and/or expected performance of the officer, and retention considerations. Grantees are required to sign confidentiality, nonsolicitation and noncompetition agreements in connection with receipt of the restricted stock grants to preclude actions detrimental to the Company. The Compensation Committee does not award restricted stock grants during any black-out period under our insider trading policy. We do not release material, nonpublic information for the purpose of affecting the value of executive compensation, nor do we award restricted stock grants to executives in coordination with the release of material, nonpublic information. Moreover, under our insider trading policy, executive officers, directors and immediate family members of the Company may not buy or sell our stock during a trading period beginning fifteen days before the end of a fiscal quarter until two business days following the release of quarterly earnings information. Trading by directors and executive officers of the Company is also prohibited during designated periods when they possess material, nonpublic information about the Company. On January 31, 2016 and 2017, each nonemployee director (other than directors Doody, Gormley and Nichols who became directors on April 1, 2017) received 907 and 481 restricted stock grants, respectively (see “Director Compensation” on page 98). These nonemployee director grants vest over a three year period from the date of grant. 89 Restricted Stock-related Payments. Under the Company’s stock grant plans in effect until April 2013, the Company agreed to pay to the holders of restricted stock granted by the Company a cash amount equal to 25% of the then fair market value of any shares vesting within thirty days after those shares vest. The Company pays that amount to provide the holder of vested shares a source of funds to pay the federal income taxes due with respect to compensation income recognized upon the vesting of the shares. See footnote 4 to the "Summary Compensation Table" on page 94. Independent Bank Group 401(k) Profit Sharing Plan. The Independent Bank Group 401(k) Profit Sharing Plan, or the 401(k) Plan, is designed to provide retirement benefits to all eligible full-time and part-time employees. The 401(k) Plan provides employees the opportunity to save for retirement on a tax-favored basis. The Company’s named executive officers, all of whom were eligible to participate in the 401(k) Plan during 2017, 2016 and 2015, may elect to participate in the 401(k) Plan on the same basis as all other employees. Employees may defer from 1% to 100% of their compensation to the 401(k) Plan up to the applicable Internal Revenue Service limit. The Company matches from 50% to 100% of an employee’s annual contribution to the 401(k) Plan, depending on the employee’s years of service with the Company, up to a total of 6% per annum of the employee’s eligible salary. The Company makes its matching contributions in cash, and that contribution is invested according to the employee’s current investment allocation. Beginning in 2014, the 401(k) Plan permits investments in Company common stock. The Company made contributions to its named executive officers’ accounts in the 401(k) plan in 2017, 2016 or 2015 in varying amounts depending on the amounts of the contributions made by the named executive officers to their respective 401(k) Plan accounts. The Company does not maintain any defined benefit plan, actuarial benefit plan, supplemental executive retirement plan or deferred compensation plan for the Company’s named executive officers or any other employees. Moreover, the Company has no plan, agreement and other arrangement with any of the Company’s named executive officers relating to the payments of any amounts upon the retirement of such named executive officer from employment with the Company or any other separation from service with the Company. Executive Employment Agreement, Award Agreements and Potential Payments Upon a Change in Control. The Company does not have employment agreements with any of the Company’s named executive officers other than Mr. James C. White, Executive Vice President and Chief Operations Officer of the Company. The other named executive officers of the Company identified herein are employees “at will” of the Company. The compensation that the Company pays to its named executive officers is determined at the discretion of the Company’s board of directors based upon the Compensation Committee’s recommendation. Mr. White’s employment agreement with the Company is for an indefinite term and may be terminated by either party at any time on thirty days’ prior written notice. The agreement provides for Mr. White to receive a salary of $265,000 per annum and to be eligible to receive an annual incentive bonus if he and the Company attain pre-established performance goals for the year in question. The annual bonus amount will be determined by the Company’s board of directors based on its review of the extent to which the annual performance goals have been attained. The target amount of the annual bonus is approximately 50% of Mr. White’s annual base salary, with any bonus paid being payable 65% in cash and 35% in restricted shares of the Company common stock that will vest if Mr. White remains employed by the Company for three years after the restricted shares are awarded. Mr. White’s employment agreement also provided for the grant of 12,000 restricted shares of Company common stock to Mr. White that will fully vest if Mr. White remains employed by the Company for five years after their grant. In connection with the issuance of the shares of restricted stock the Company issued to the Company’s executive officers and certain senior officers of Independent Bank pursuant to the Equity Incentive Plan, the Company requires that each recipient of an award enter into an award agreement that includes noncompetition and nonsolicitation covenants. Each such agreement provides that the award recipient will not compete with the Company for a specified period following the termination of his or her employment with the Company or Independent Bank. Competition for such purposes is defined to include such person acting as an officer, director, manager or employee of, or a consultant to, any bank holding company, bank or other financial institution conducting banking operations in the Company’s market areas in the State of Texas. The periods for which such competition is prohibited is two years for David R. Brooks, one year for each of Daniel W. Brooks, Michelle S. Hickox, Brian E. Hobart and James C. White and three months for those award recipients who are senior officers of Independent Bank. The various award recipients also agree not to solicit other employees or customers of the Company or Independent Bank. The nonsolicitation period for the Company’s executive officers is one year following the termination of their employment with the Company or Independent Bank. The nonsolicitation period for officers of Independent Bank is set by the Compensation Committee for each officer and ranges from three months to one year following termination of employment. 90 The Company has entered into Change in Control Agreements (the “Change in Control Agreements”) with David R. Brooks, Chairman, Chief Executive Officer and President, Daniel W. Brooks, Vice Chairman and Chief Risk Officer, Brian E. Hobart, Vice Chairman and Chief Lending Officer, and Michelle S. Hickox, Executive Vice President and Chief Financial Officer , and James C. White, Executive Vice President and Chief Operations Officer, (each individually, the “Executive”). Each of the Change in Control Agreements provides, among other things, that if, within twelve months following the occurrence of a Change in Control of the Company (see below), (a) the Company terminates the Executive’s employment without Cause (see below) or the Executive terminates his or her employment for Good Reason (see below) and (b) the Executive signs and allows to become effective a general release of all known and unknown claims in favor of the Company and its affiliates, then (i) the Executive will be entitled to a lump sum cash payment in an amount equal to three times the sum, for David R. Brooks, or two times the sum, for Daniel W. Brooks, Brian E. Hobart, Michelle S. Hickox and James C. White, of (x) the Executive’s current annual base salary, plus (y) the Executive’s target total annual bonus for the year of termination, (ii) all of Executive’s unvested grants of restricted stock will become vested and will no longer be subject to restriction or forfeiture, and (iii) Executive shall continue to be a participant in the Independent Bank Survivor Benefit Plan such that, upon Executive’s death and provided certain thresholds are met, the Company will pay to the Executive’s beneficiary, as a survivor benefit, a single lump sum cash payment equal to the Executive’s annual base salary in effect on the date of the termination of the Executives’ employment. Each of the Change in Control Agreements provides further that the amount of payments and benefits payable to the Executive is subject to reduction to the extent necessary to ensure that such amount does not constitute a “parachute payment” as defined in Section 280G of the Internal Revenue Code of 1986, as amended. We believe our Change in Control Agreements are conservative when compared to the competitive market. We view them as necessary to ensure the continued focus of our executives on making the appropriate strategic decisions for the Company even if the decision involves a change in control. As used in the Change in Control Agreements, a “Change in Control” is defined as one or more of the following: • • • the acquisition by any person or entity of beneficial ownership of 50% or more of either (a) the then outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (b) the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, that the following shall not constitute a Change of Control: (w) any acquisition directly from the Company, (x) any acquisition by the Company, (y) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any of its subsidiaries, or (z) any acquisition by any corporation pursuant to a transaction which complies with the Change in Control Exceptions (defined below); During any period of 2 consecutive years (not including any period prior to February 21, 2013) individuals who constituted the Board on February 21, 2013 (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to February 21, 2013 whose election, or nomination for election by the Company’s shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a person or entity other than the Board; Consummation of a reorganization, merger, statutory share exchange or consolidation or similar corporate transaction involving the Company or any of its subsidiaries, a sale or other disposition of all or substantially all of the assets of the Company, or the acquisition of assets or stock of another entity by the Company or any of its Subsidiaries (each a “Business Combination”), in each case, unless, following such Business Combination, (A) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of, respectively, the then outstanding shares of Common Stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the entity resulting from such Business Combination (including a corporation that as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, (B) no person (excluding any employee benefit plan (or related trust) of the Company or such entity resulting from such Business Combination) beneficially owns, directly or indirectly, 50% or more of, respectively, the then outstanding shares of common stock of the entity resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such entity except to the extent that such ownership existed prior to the Business Combination and 91 (C) at least a majority of the members of the Board of Directors or other governing body of the entity resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination (collectively, clauses (a), (b) and (c) are referred to as “Change in Control Exceptions”); or Approval by the shareholders of the Company of a complete liquidation or dissolution of the Company. • As used in the Change in Control Agreements, “Cause” means termination of an employee due to any of the following after the Company provides notice to the employee by the Company, specifying such Cause with reasonable particularity, and giving the employee 30 days from the receipt thereof in which to cure the act or omission complained of, unless the act or omission of its very nature cannot be cured: • material act of self-dealing between the Company and the employee which is not disclosed in full to, and • • • • • • • approved by, the Board; deliberate falsification by the employee of any records or reports; fraud on the part of the employee against the Company or any of its subsidiaries or affiliates; theft, embezzlement or misappropriation by the employee of any funds of the Company, or conviction of any felony; execution of any document transferring, or creating any material lien or encumbrance on, any material property of the Company, not in the ordinary course of business, without authorization of the Board; engagement by the employee in inappropriate behavior which is found by the Company after due investigation to be sexual harassment or assault; declaration by an independent medical authority that the employee is addicted to drugs or alcohol; or any recommendation or suggestion by any bank regulatory authority that the employee’s employment must be terminated. As used in the Change in Control Agreements, “Good Reason” means termination by an employee due to any of the following after the employee has provided written notice to the Company of the existence of the circumstances alleged to constitute Good Reason and the Company has had at least 30 days from the date on which such notice is provided to cure such circumstances (if the employee does not terminate his or her employment within 90 days of the first occurrence of such circumstances, the employee is deemed to have waived his or her right to terminate for Good Reason with respect to such circumstances): • • • • the assignment to the employee of any duties or responsibilities, other than in connection with a promotion, inconsistent in any material respect with employees position (including status, offices, titles and reporting relationships), authority, duties or responsibilities in effect immediately prior to a Change in Control, or any other action by the Company which results in a material diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly following receipt of notice thereof given by the employee; a reduction in the executive’s compensation and benefits which were in effect immediately prior to a Change of Control; the material breach by the Company of any provision of the Change in Control Agreement applicable to the employee; or the requirement that the employee’s principal place of employment be based at a location further than 30 miles from the Company’s principal office immediately prior to the Change in Control. Each Change in Control Agreement expires three years following the date on which such agreement was executed. Unless previously terminated, upon the expiration of the term thereof, each Change in Control Agreement will renew for successive one-year renewal terms provided that the Company’s Compensation Committee explicitly reviews such agreement and expressly approves each extension within a 90-day period prior to the end of such initial or renewal term. Each Change in Control Agreement automatically terminates without further action by the Company if the employee’s employment is terminated: by the Company for Cause or upon the employee’s death or disability or voluntarily by the employee without Good Reason. Under the Change in Control Agreements, the Company is not obligated to make any payment to the employees subject to such agreements if any such payments or benefits to the employee would constitute a “golden parachute payment” as defined in 12 CFR §359 unless such payment can be made in compliance with such regulation. The Company is obligated to use commercially reasonable efforts to obtain any regulatory approvals required to enable it to make such payments under the applicable Change in Control Agreement. 92 In addition to the amounts payable under the Change in Control Agreements, the Company’s Equity Incentive Plan generally provides that, upon a Change in Control satisfying the requirements of such plan, all restrictions, deferrals of settlement and forfeiture conditions applicable to shares of restricted stock granted under such plan will lapse and such shares will be deemed fully vested as of the time of the Change in Control, except with respect to grants subject to the achievement of performance goals that the successor entity assumes or for which the successor entity provides a substitute (pursuant to the terms and conditions of such plan). Benefits and Perquisites. The Company’s named executive officers are eligible to participate in the same benefit plans designed for all of the Company’s full-time employees, including health, dental, vision, disability and basic group life insurance coverage. The Company does not provide the named executive officers with any health and welfare benefits that are not generally available to its other employees. The Company also provides its employees, including its named executive officers, with a 401(k) plan to assist its employees, including its named executive officers, in planning for retirement and securing appropriate levels of income during retirement. The purpose of the Company’s employee benefit plans is to help the Company attract and retain quality employees, including executives, by offering benefit plans similar to those typically offered by the Company’s competitors. None of the perquisites or benefits paid or provided to any of the Company’s named executive officers exceeded $25,000 in amount for 2017, 2016 or 2015. Insurance Premiums. Independent Bank maintains bank-owned life insurance policies with respect to certain of the Company’s named executive officers. Although Independent Bank is the named beneficiary of each of those policies, the Company has agreed with each of those named executive officers that if the officer dies while employed by Independent Bank, the Company will pay such named executive officer’s estate an amount equal to the amount of that officer’s salary for the year in which his or her death occurs out of the benefits Independent Bank receives under such policy. Say on Pay. The 2018 annual meeting of shareholders will include the Company’s first advisory “say-on-pay” proposal. It is expected that, in the future, the Compensation Committee will incorporate results of this advisory vote as one of many factors considered in connection with the discharge of its responsibilities. Deductibility of Compensation. Section 162(m) of the Code generally limits the deductibility of compensation paid by a public company during a tax year to its chief executive officer and its other three most highly compensated executive officers for that tax year. Under Section 162(m) of the Code, the annual compensation paid to any of these specified executives will be deductible only to the extent that it does not exceed $1,000,000. However, under Section 162(m) of the Code qualifying performance-based compensation, including income from stock options and other performance based awards, may be deductible if the conditions of Section 162(m) are met. Although deductibility of compensation is preferred, tax deductibility is not a primary objective of the Company’s compensation programs. The Company believes that achieving its objectives under the compensation philosophy set forth above is more important than the benefit of tax deductibility. The Company reserves the right to maintain flexibility in how it compensates its executive officers that may result in limiting the deductibility of amounts of compensation from time to time. For 2017, the Committee evaluated a variety company performance measures relating to profitability, growth, risk and strategic direction. The Committee did not believe it was appropriate or beneficial to shareholders to establish specific formulas and weighting to fund incentives. Therefore, compensation in excess of $1 million for 2017 may not be tax deductible. BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION Notwithstanding anything to the contrary set forth in any of the Company’s previous or future filings under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act that might incorporate the information in this Item 11. Executive Compensation or future filings with the SEC, in whole or in part, the following report of the Compensation Committee shall not be deemed to be incorporated by reference into any such filing. The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with management and, based on such review and discussion, the Compensation Committee has recommended to the Board that the Compensation Discussion and Analysis be included in Item 11. Executive Compensation of the Company’s Annual Report on Form 10 K. The Compensation Committee William E. Fair (Chairman) J. Webb Jennings, III G.

The amounts of bonuses for each year shown were cash bonuses earned for that year, but that were paid in the following fiscal year. The market values of the outstanding stock awards presented as of December 31, 2017, 2016 and 2015, are based on the market value of the Company’s common stock on the date of the grant which was $62.15 on January 31, 2017, $29.91 on January 29, 2016, and $31.21 on January 30, 2015. The grants awarded for each year shown were based upon the Company's and the executive's performance for the prior year. Includes 401(k) contributions, health and welfare benefits, restricted stock related payments, insurance premiums and certain perquisites and other benefits. None of these individual components of All Other Compensation exceeded $25,000 in 2016 or 2015. In 2017, the Company made payments related to payroll taxes on restricted stock vesting for Daniel W. Brooks ($68,876), Brian E. Hobart ($68,033) and Michelle S. Hickox ($60,011). (5) Mr. Brooks became President of the Company on October 3, 2016. (6) Mr. White joined the Company as Chief Operations Officer effective April 21, 2016 and the salary shown for 2016 was received for the portion of that year in which he was employed by the Company. Such salary accrued at a rate of $265,000 per annum. As a result of Mr. White being an executive officer of the Company for only 2017 and 2016, only his compensation for 2017 and 2016 is disclosed above. The market value of the outstanding stock awards presented for Mr White as of December 31, 2016 are based on the market value of the Company’s common stock on the date of the grant which was $34.78 on May 16, 2016. Grants of Plan-Based Awards The Compensation Committee grants restricted stock awards periodically.

Potential Payments upon Termination or Change in Control The following table summarizes the estimated payments to be made under each named executive officer’s change in control agreement described above. For the purposes of the quantitative disclosure in the following table, and in accordance with SEC regulations, the Company has assumed that the change in control took place on December 31, 2017, and that the price per share of its common stock was the closing market price as of that date, $67.60. Name David R. Brooks Daniel W. Brooks Brian E. Hobart Michelle S. Hickox James C. White Cash(1) $6,375,000 1,850,000 1,710,000 1,250,000 1,170,000 Equity(2) $1,488,349 557,768 488,140 396,947 703,108 Pension/ NQDC Perquisites/ Benefits Tax Reimbursement $— — — — — $— — — — — $— — — — Other(3) $— — — — — Total $7,863,349 2,407,768 2,198,140 1,646,947 1,873,108 (1) (2) (3) Cash amounts that would be paid under the Company’s existing change in control agreements upon a change in control and a qualifying termination or termination for good reason using base salary information for 2018 and the amount of the named executive officers’ 2017 annual incentive bonus. Estimates of the value that would have been recognized by our executive officers as result of the accelerated vesting of the shares of restricted stock held by such executive officers assuming a change in control occurred on December 31, 2017. The estimated value was calculated by multiplying the number of unvested shares of restricted stock held by the applicable executive officer by the closing price of our common shares on December 31, 2017, which was $67.60. The actual amounts to be paid out can only be determined at the time of such change in control. Other benefits for each executive officer, except for James C. White, include continued participation in Independent Bank’s BOLI Plan. Under this plan, if (i) an executive dies before reaching age 65 and (ii) Independent Bank actually receives sufficient proceeds from a life insurance policy insuring the life of such executive, then Independent Bank shall pay to such executive’s designated beneficiary, as a survivor benefit, a single lump sum cash payment equal to such executive’s annual base salary in effect on the date of the termination of such executive’s employment with Independent Bank within 30 days after such executive’s death. Chief Executive Officer Compensation The compensation that the Company paid David R. Brooks, the Company’s Chairman and Chief Executive Officer, was reviewed and determined by the Compensation Committee. The compensation paid reflects the Compensation Committee’s view of Mr. Brooks’ continuing contribution to the success of the Company’s operations. That compensation, including Mr. Brooks’ salary for 2017 and his cash bonus and equity awards for 2017, are intended to compensate Mr. Brooks for his successful leadership of the Company and Independent Bank and management of their operations, as reflected by the Company’s growth in assets, deposits and net income, the expansion of the Company’s markets, the maintenance of the Company’s strong asset quality and credit culture despite volatile economic conditions during 2017, and the successful negotiation of the Carlile acquisition. 97 Director Compensation The following table sets forth information regarding 2017 compensation for those of the Company’s directors during 2017 who were not named executive officers of the Company for 2017: Director Compensation Table Name Fees Earned or Paid in Cash $50,000 Stock Awards(1) $29,894 45,000 50,000 45,000 55,000 45,000 45,000 45,000 50,000 45,000 — 29,894 — $29,894 $29,894 — $29,894 $29,894 $29,894 Douglas A.

The Company’s directors were reimbursed for the reasonable out-of-pocket expenses they incur in connection with their service as directors, including travel costs to attend the meetings of the board of directors and committees. The Company’s directors who were also the Company’s named executed officers did not receive fees or other compensation for their service as directors of the Company. Mr. David R. Brooks and Mr. Daniel W. Brooks, who are directors and executive officers of the Company, do not receive any compensation in their capacity as directors of the Company. Compensation Committee Interlocks and Insider Participation During 2017, no executive officer of the Company served as (1) a member of a compensation committee (or other Board committee performing equivalent functions or, in the absence of any such committee, the entire Board) of another entity, one of whose executive officers served on the Company’s Compensation Committee, (2) a director of another entity, one of whose executive officers served on the Company’s Compensation Committee or (3) a member of the compensation committee (or other Board committee performing equivalent functions or, in the absence of any such committee, the entire Board) of another entity, one of whose executive officers served as a director of the Company. In addition, none of the members of the Compensation Committee (a) was an officer or employee of the Company or any of its subsidiaries in 2017, (b) was formerly an officer or employee of the Company or any of its subsidiaries or (c) had any relationship that required disclosure under “Certain Relationships and Related Transactions,” except as is disclosed under such section for William E.

All these shares are subject to a Voting and Lock Up Agreement, dated November 21, 2016 between LEP Carlile Holdings, LLC and the Company which restricts the transfer of these shares until April 1, 2018, without the prior written consent of the Company. (15) According to a Schedule 13G filed by Wellington Management Group LLP with the SEC on February 8, 2018, as the holding company for Wellington Group Holdings LLP, Wellington Investment Advisors LLP and Wellington Management Global Holdings, Ltd. These shares are owned of record by clients of the following investment advisors (collectively, the Wellington Investment Advisors): Wellington Management Company LLC, Wellington Management Canada LLC, Wellington Management Singapore Pte Ltd, Wellington Management Hong Kong Ltd, Wellington Management International Ltd., Wellington Management Japan Pte Ltd and Wellington Management Australia Pty Ltd. Wellington Investment Advisors Holdings LLP controls directly, or indirectly through Wellington Management Global Holdings, Ltd., the Wellington Investment Advisers; Wellington Investment Advisors Holdings LLP is owned by Wellington Group Holdings LLP; Wellington Group Holdings LLP is owned by Wellington Management Group LLP. There are no arrangements currently known to us, the operation of which may at a subsequent date result in a change in control of the Company. The Company’s policies prohibit directors and executive officers from holding shares of Company common stock in a margin account. This prohibition recognizes the risk that directors or executives may be forced to sell shares to meet a margin call, which could negatively impact the Company’s stock price and may violate insider trading laws and policies. However, the Company’s policies do not prohibit the pledge of shares of Company common stock by directors or executive officers to secure personal indebtedness. The indebtedness incurred by directors and executive officers who have pledged their shares is indebtedness incurred to purchase Company common stock or for personal reasons and is not part of a hedging strategy to immunize the director or executive officer from economic exposure with respect to the Company’s common stock. Further, the pledge of shares typically does not result in a forced sale by the director or executive officer in the event of default on the loan. Rather, upon default, other arrangements typically are made such as the pledge of additional collateral to secure the loan. Ultimately, if suitable arrangements cannot be made and if the loan remains in default, the lender may foreclose upon and take ownership of the pledged shares. The lender may or may not sell the foreclosed shares. Presumably, the lender would sell the foreclosed shares only under circumstances that would maximize the value of the foreclosed shares. For these reasons, the pledge of shares does not present the same risks as holding shares in a margin account, and the Company believes that the pledging of shares of Company common stock by directors and executive officers does not present undue risk to the Company or its shareholders. ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE Related Person Transaction Review Policy The Company has adopted a formal written policy concerning related party transactions. A related party transaction is a transaction, arrangement or relationship or a series of similar transactions, arrangements or relationships in which the amount involved exceeds $120,000, in which the Company or one of the Company’s consolidated subsidiaries participates (whether or not the Company or the subsidiary is a direct party to the transaction), and in which a director, nominee to become a director, executive officer or employee of the Company or one of the Company’s consolidated subsidiaries or any of his or her immediate family members or any entity that any of them controls or in which any of them has a substantial beneficial ownership interest has a direct or indirect material interest, or in which any person who is the beneficial owner of more than 5% of the Company’s voting securities or a member of the immediate family of such person has a direct or indirect material interest. A copy of the Company’s policy may be found on the Company’s website at www.ibtx.com. The Company’s policy requires the Company’s Corporate Governance and Nominating Committee to ensure that the Company maintains an ongoing review process for all related party transactions for potential conflicts of interest and requires that the Corporate Governance and Nominating Committee pre-approve any such transactions or, if for any reason pre-approval is not obtained, to review, ratify and approve or cause the termination of such transactions. The Company’s Corporate Governance and Nominating Committee evaluates each related party transaction for the purpose of recommending to the disinterested members of the Company’s board of directors whether the transaction is fair, reasonable and permitted to occur under the Company’s policy, and should be pre-approved or ratified and approved by the Company’s board of directors. 100 Relevant factors considered relating to any approval or ratification include the benefits of the transaction to the Company, the terms of the transaction and whether the transaction will be or was on an arm’s-length basis and in the ordinary course of the Company’s business, the direct or indirect nature of the related party’s interest in the transaction, the size and expected term of the transaction and other facts and circumstances that bear on the materiality of the related party transaction under applicable law and listing standards. Related party transactions entered into, but not approved or ratified as required by the Company’s policy concerning related party transactions, will be subject to termination by us or the relevant subsidiary, if so directed by the Company’s Corporate Governance and Nominating Committee or the Company’s board of directors, taking into account factors as deemed appropriate and relevant. Lending and other banking transactions in the ordinary course of business and consistent with the insider loan provisions of Regulation O of the Board of Governors of the Federal Reserve System are not treated as related party transactions under this policy and, instead, these transactions are monitored and approved, if necessary, by Independent Bank’s board of directors. In addition, any transaction in which the rates or charges are determined by competitive bids are not subject to approval under the policy. The Company’s directors, officers, beneficial owners of more than 5% of the Company’s voting securities and their respective associates were customers of and had transactions with the Company in the past, and additional transactions with these persons are expected to take place in the future. All outstanding loans and commitments to loan with these persons were made in the ordinary course of business, were made on the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company or Independent Bank and did not involve more than the normal risk of collectibility or present other unfavorable features. All such loans are approved by Independent Bank’s board of directors in accordance with bank regulatory requirements. Similarly, all certificates of deposit and depository relationships with these persons were made in the ordinary course of business and involved substantially the same terms, including interest rates, as those prevailing at the time for comparable depository relationships with persons not related to the Company or Independent Bank. Related Person Transactions The following is a description of certain transactions in which the Company participated in 2017 or is currently proposed and in which one or more of the Company’s directors, executive officers or beneficial holders of more than 5% of the Company’s capital stock, or their immediate family members or entities affiliated with them, had or will have a direct or indirect material interest. IBG Aircraft. IBG Aircraft Company III, a subsidiary of Independent Bank, or IBG Aircraft, owns an airplane. The Company and Independent Bank use the airplane to facilitate the travel of the Company’s and Independent Bank’s executives for corporate purposes related to the Company’s business. Independent Bank uses the aircraft to facilitate the travel of Independent Bank employees to and from Independent Bank’s locations across Texas and Colorado. David R. Brooks elects to receive a portion of his cash bonus in the form of personal use of the aircraft. Under this arrangement, the Compensation Committee establishes the cash bonus for Mr. Brooks. Mr. Brooks is then charged a rate per flight hour for use of the aircraft (computed on an hourly basis and including fuel, maintenance reserves and other operating costs) as established by an aviation committee, a joint committee of the Company’s and Independent Bank’s boards of directors comprised of David R. Brooks, William E. Fair and David Wood. This amount is then charged against Mr. Brook’s bonus amount, reducing the cash portion of the bonus awarded to Mr. Brooks. The Compensation Committee and the Corporate Governance and Nominating Committee have reviewed and approved this arrangement, and the Company believes that this arrangement is in compliance with third party regulations established by bank regulatory agencies. Branch Lease. Independent Bank leases its Woodway Branch in Waco from Waco Fairbank Realty, Ltd., of which William E. Fair, one of the Company’s directors, is a limited partner. Independent Bank pays rent for this 5,462 square foot facility, at the rate of $27.50 per square foot, or $150,204 annually, from 2016 - 2018, $29.00 per square foot, or $158,400 annually, from 2018 - 2021, and $30.60 per square foot plus an amount based upon the increase in consumer price index, or approximately $167,136 annually, from 2021 - 2026. Additionally, in March 2011, Independent Bank sold a 2,000 square foot office building to Mr. Fair’s IRA. Independent Bank had previously foreclosed on the building and was holding it as other real estate, or ORE. The purchase price was $200,000. Independent Bank had marketed the property with two separate real estate agents that produced offers from unrelated parties for less than $200,000. Mr. Fair’s IRA also paid the closing costs. As part of the transaction, Independent Bank loaned Mr. Fair’s IRA $150,000 at a fixed interest rate of 5.50%. Principal and interest is payable monthly on the basis of fifteen years with a balloon payment that was initially due in May 2016. In December 2011, the loan was modified to lower the interest rate to 4.75% and to extend the maturity date to December 2016. In December 2016, the loan was modified to extend the maturity date to January 1, 2025 and changed the interest rate to be the floating Wall Street Journal prime rate (4.5% at December 31, 2017). The largest outstanding principal balance of the loan in 2017, was $102,310 on January 1, 2017, and the outstanding principal balance of the loan at February 26, 2018, was $90,674. The amount of principal and interest paid by Mr. Fair’s IRA in 2017 was $9,821 and $3,734, respectively. The Company believes that these 101 arrangements are at least as favorable to Independent Bank as could have been arranged with unrelated third parties and are in compliance with third party regulations for transactions with directors and their affiliates established by bank regulatory agencies. Director Independence Under the rules of the Nasdaq Global Select Market, independent directors must comprise a majority of the Company’s board of directors. The rules of the Nasdaq Global Select Market, as well as those of the SEC, also impose several other requirements with respect to the independence of directors. The Company’s board of directors has evaluated the independence of its members based upon the rules of the Nasdaq Global Select Market and the SEC. Applying these standards, the board of directors has affirmatively determined that, with the exception of David R. Brooks and Daniel W. Brooks, each of the Company’s directors set forth under Item 10. Directors, Executive Officers and Corporate Governance is an independent director, as defined under the applicable rules. The board of directors determined that each of David R. Brooks and Daniel W. Brooks does not qualify as an independent director because of his position as an executive officer of the Company and Independent Bank. 102 ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES Fees Paid to Independent Registered Public Accounting Firm The Audit Committee has reviewed the following audit and nonaudit fees that the Company has paid to RSM US LLP for 2016 and 2017 for purposes of considering whether such fees are compatible with maintaining the auditor’s independence. The policy of the Audit Committee is to pre-approve all audit and nonaudit services performed by RSM US LLP before the services are performed, including all of the services described under “Audit Fees,” “Audit Related Fees,” “Tax Fees” and “All Other Fees” below. Audit Fees. Estimated fees billed for service rendered by RSM US LLP for the reviews of the Company’s quarterly reports filed on Form 10-Q, the audit of the consolidated annual financial statements of the Company and services provided for other SEC filings were $486,500 and $697,600 for 2016 and 2017, respectively.

Audit Committee Pre-Approval Policy The Audit Committee has established a policy and related procedures regarding the pre-approval of all audit, audit- related and nonaudit services to be performed by the Company’s independent auditors. The Audit Committee will approve the maximum aggregate amount of the costs that may be incurred under a general pre-approval of certain audit services. Any proposed audit services for which the cost to the Company would exceed these levels or amounts, or services that have not received general pre-approval, requires specific pre-approval by the Audit Committee. The term of any general pre-approval is twelve (12) months from the stated date of pre-approval, unless the Audit Committee considers a different period and specifically states otherwise. The Audit Committee annually reviews and pre- approves the services, and the associated cost levels or budgeted amounts, that may be provided by its independent auditor without obtaining specific pre-approval from the Audit Committee. The Audit Committee adds to or subtracts from the list of general pre-approved services from time to time, based on subsequent determinations. In addition to the annual audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval for audit-related services and other audit services. Unless granted general pre-approval, all audit- related services and other audit services must be specifically pre-approved by the Audit Committee. All nonaudit services must be specifically pre-approved by the Audit Committee. The Company’s independent auditor may not be engaged to provide any service that is prohibited by applicable law to be provided to an audit client by an independent auditor. The Audit Committee may delegate pre-approval authority to one or more of its members. All requests or applications for services to be provided by the independent auditor that do not require specific approval by the Audit Committee will be submitted to the Chief Financial Officer of the Company. The Chief Financial Officer will determine, upon consultation with the chairman of the Audit Committee, whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. 103 ITEM 15.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Independent Bank Group, Inc. and its subsidiaries (the Company) as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, changes in stockholders' equity and cash flows for each of the three years in the period ended December 31, 2017, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 27, 2018 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ RSM US LLP We or our predecessor firms have served as the Company’s auditor since at least 2001.

Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Note 1. Summary of Significant Accounting Policies Nature of Operations: Independent Bank Group, Inc. (IBG) through its subsidiary, Independent Bank, a Texas state banking corporation (Bank) (collectively known as the Company), provides a full range of banking services to individual and corporate customers in North, Central and Southeast, Texas areas and along the Colorado Front Range, through its various branch locations in those areas. The Company is engaged in traditional community banking activities, which include commercial and retail lending, deposit gathering, investment and liquidity management activities. The Company’s primary deposit products are demand deposits, money market accounts and certificates of deposit, and its primary lending products are commercial business and real estate, real estate mortgage and consumer loans. Basis of Presentation: The accompanying consolidated financial statements include the accounts of IBG, its wholly-owned subsidiaries, the Bank, IBG Adriatica Holdings, Inc. (Adriatica) and Carlile Capital, LLC and the Bank’s wholly-owned subsidiaries, IBG Real Estate Holdings, Inc., IBG Real Estate Holdings II, Inc., IBG Aircraft Company III, Preston Grand, Inc., CFRH II, LLC, McKinney Avenue Holdings, Inc. and its wholly owned subsidiary, McKinney Avenue Holdings SPE 1, Inc.. Adriatica, CFRH II, LLC, McKinney Avenue Holdings, Inc. and its subsidiary are currently not active entities. During the third quarter 2017, IBG Real Estate Holdings II, Inc. was formed to hold the real property for the new corporate headquarters. On April 1, 2017, the Company acquired Carlile Bancshares, Inc. (Carlile) and its wholly owned subsidiaries, Carlile Capital, LLC and Northstar Bank of Texas (Northstar) and its wholly owned subsidiaries, Goldome Financial, LLC (Goldome) and CFRH II, LLC. Carlile has been merged into the Company and dissolved and Northstar has been merged with the Bank as of acquisition date. Carlile Capital and CFRH II, LLC were formed to hold and manage non-performing assets, including loans and other real estate owned and Goldome is a mortgage warehouse purchase company. During the fourth quarter 2017, Goldome was merged with the Bank and dissolved. See Note 20, Business Combination for more details of the Carlile acquisition. All material intercompany transactions and balances have been eliminated in consolidation. In addition, the Company wholly- owns IB Trust I (Trust I), IB Trust II (Trust II), IB Trust III (Trust III), IB Centex Trust I (Centex Trust I), Community Group Statutory Trust I (CGI Trust I), Northstar Statutory Trust II (Northstar Trust II) and Northstar Statutory Trust III (Northstar Trust III). Northstar Trust II and Northstar Trust III were acquired in the acquisition of Carlile Bancshares. The Trusts were formed to issue trust preferred securities and do not meet the criteria for consolidation (see Note 12). Accounting standards codification: The Financial Accounting Standards Board's (FASB) Accounting Standards Codification (ASC) is the officially recognized source of authoritative U.S. generally accepted accounting principles (GAAP) applicable to all public and non-public non-governmental entities. Rules and interpretive releases of the SEC under the authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. All other accounting literature is considered non-authoritative. Citing particular content in the ASC involves specifying the unique numeric path to the content through the Topic, Subtopic, Section and Paragraph structure. Segment Reporting: The Company has one reportable segment. The Company’s chief operating decision-maker uses consolidated results to make operating and strategic decisions. Reclassifications: Certain prior period financial statement amounts have been reclassified to conform to current period presentation. The reclassifications have no effect on net income or stockholders' equity as previously reported. Use of estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. The material estimates included in the financial statements relate to the allowance for loan losses, the valuation of goodwill and valuation of assets and liabilities acquired in business combinations. Cash and cash equivalents: For the purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks and federal funds sold. All highly liquid investments with an initial maturity of less than ninety days are considered to be cash equivalents. The Company maintains deposits with other financial institutions in amounts that exceed FDIC insurance coverage. The Company's management monitors the balance in these accounts and periodically 114 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) assesses the financial condition of the other financial institutions. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risks on cash or cash equivalents. Certificates of deposit: Certificates of deposit are FDIC insured deposits in other financial institutions that mature within 18 months and are carried at cost. Securities: Securities classified as available for sale are those debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Securities available for sale are reported at fair value with unrealized gains or losses reported as a separate component of other comprehensive income, net of tax. The amortization of premiums and accretion of discounts, computed by the interest method over their contractual lives, are recognized in interest income. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings on the trade date. In estimating other than temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent of the Company to retain its investment and whether it is more likely than not the Company will be required to sell its investment before its anticipated recovery in fair value. When the Company does not intend to sell the security, and it is more likely than not that it will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other than temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. Loans held for sale: The Company originates residential mortgage loans that may subsequently be sold to unaffiliated third parties. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Mortgage loans held for sale are sold without servicing rights retained. Gains and losses on sales of loans are recognized in noninterest income at settlement dates and are determined by the difference between the sales proceeds and the carrying value of the loans. Acquired loans: Acquired loans from the transactions accounted for as a business combination include both non-performing loans with evidence of credit deterioration since their origination date and performing loans. The Company is accounting for the non-performing loans acquired in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. The performing loans are being accounted for under ASC 310-20, Nonrefundable Fees and Other Costs, with the related difference in the initial fair value and unpaid principal balance (the discount) recognized as interest income on a level yield basis over the life of the loan. At the date of the acquisition, the acquired loans are recorded at their fair value and there is no carryover of the seller's allowance for loan losses. Purchased credit impaired loans are accounted for individually. The Company estimates the amount and timing of undiscounted expected cash flows for each loan, and the expected cash flows in excess of fair value is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the expected cash flows decrease, an impairment loss is recorded. If the expected cash flows increase, it is recognized as part of future interest income. Loans, net: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal balance adjusted for the allowance for loan losses and deferred loan fees. Fees and costs associated with originating loans are generally recognized in the period they are incurred, except in the Houston market, former Grand Bank and Carlile branches, which fees are deferred. The provisions of ASC 310, Receivables, generally provide that such fees and related costs be deferred and recognized over the life of the loan as an adjustment of yield. 115 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Management believes that not deferring such amounts and amortizing them over the life of the related loans does not materially affect the financial position or results of operations of the Company. Allowance for loan losses: The allowance for loan losses is maintained at a level considered adequate by management to provide for probable loan losses. The allowance is increased by provisions charged to expense. Loans are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance. The provision for loan losses is the amount, which, in the judgment of management, is necessary to establish the allowance for loan losses at a level that is adequate to absorb known and inherent risks in the loan portfolio. See Note 6 for further information on the Company's policies and methodology used to estimate the allowance for loan losses. Premises and equipment, net: Land is carried at cost. Bank premises, furniture and equipment and aircraft are carried at cost, less accumulated depreciation computed principally by the straight-line method over the estimated useful lives of the assets, which range from three to thirty years. Leasehold improvements are carried at cost and are depreciated over the shorter of the estimated useful life or the lease period. Long-term assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Other real estate owned: Real estate properties acquired through, or in lieu of, loan foreclosure are initially recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations of other real estate owned and impairment charges on other real estate are included in noninterest expense. Gains and losses on sale of other real estate are included in noninterest income. Goodwill and core deposit intangible, net: Goodwill represents the excess of costs over fair value of net assets of businesses acquired. Goodwill is tested for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. Core deposit intangibles are acquired customer relationships arising from bank acquisitions and are amortized on a straight-line basis over their estimated useful lives of ten years. Core deposit intangibles are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. Restricted stock: The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB of Dallas and Independent Bankers Financial Corporation stock do not have readily determinable fair values as ownership is restricted and they lack a ready market. As a result, these stocks are carried at cost and evaluated periodically by management for impairment. Both cash and stock dividends are reported as income. Bank-owned life insurance: Bank-owned life insurance is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the net cash surrender value of the policies, as well as insurance proceeds received are reflected in noninterest income. Mortgage banking revenue: This revenue category reflects the Company's mortgage production revenue, including fees and income derived from mortgages originated with the intent to sell and gains on sales of mortgage loans. Interest earned on mortgage loans is recorded in interest income. 116 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Income taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities (excluding deferred tax assets and liabilities related to business combinations or components of other comprehensive income). Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. The effect of a change in tax rates on deferred assets and liabilities is recognized in income taxes during the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the expected amount more likely than not to be realized. Realization of deferred tax assets is dependent upon the level of historical income, prudent and feasible tax planning strategies, reversals of deferred tax liabilities and estimates of future taxable income. The Company evaluates uncertain tax positions at the end of each reporting period. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. Any interest and/ or penalties related to income taxes are reported as a component of income tax expense. Loan commitments and related financial instruments: In the ordinary course of business, the Company has entered into certain off-balance-sheet financial instruments consisting of commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received. Management estimates losses on off-balance-sheet financial instruments using the same methodology as for portfolio loans. Estimated losses on off-balance-sheet financial instruments are recorded by charges to the provision for losses and credits to other liabilities in the Company's consolidated balance sheet. There were no estimated losses on off-balance sheet financial instruments as of December 31, 2017 or 2016. Stock based compensation: Compensation cost is recognized for restricted stock awards issued to employees based on the market price of the Company's common stock on the grant date. Stock-based compensation expense is generally recognized using the straight-line method over the requisite service period for all awards. The impact of forfeitures of stock-based payment awards on compensation expense is recognized as forfeitures occur. Transfers of financial assets: Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Advertising costs: Advertising costs are expensed as incurred. Business combinations: The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100% of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Where amounts allocated to assets acquired and liabilities assumed is greater than the purchase price, a bargain purchase gain is recognized. Adjustments identified during the measurement period are recognized in the reporting period in which the adjustment amounts are determined. Acquisition-related costs are expensed as incurred. Comprehensive income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. Gains and losses on available for sale securities are reclassified to net income as the gains or losses are realized upon sale of the securities. Other than temporary impairment charges are reclassified to net income at the time of the charge. 117 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Fair values of financial instruments: Accounting standards define fair value, establish a framework for measuring fair value in U.S. generally accepted accounting principles, and require certain disclosures about fair value measurements (see Note 17, Fair Value Measurements). In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Subsequent events: Companies are required to evaluate events and transactions that occur after the balance sheet date but before the date the financial statements are issued. They must recognize in the financial statements the effect of all events or transactions that provide additional evidence of conditions that existed at the balance sheet date, including the estimates inherent in the financial statement preparation process. Entities shall not recognize the impact of events or transactions that provide evidence about conditions that did not exist at the balance sheet date but arose after that date. The Company has evaluated subsequent events through the date of filing these financial statements with the SEC and noted no subsequent events requiring financial statement recognition or disclosure, except as disclosed in Note 23. Earnings per share: Basic earnings per common share are net income divided by the weighted average number of common shares outstanding during the period. The unvested share-based payment awards that contain rights to non forfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock warrants. The participating nonvested common stock was not included in dilutive shares as it was anti-dilutive for the years ended December 31, 2017 and 2016. Proceeds from the assumed exercise of dilutive stock warrants are assumed to be used to repurchase common stock at the average market price. The following table presents a reconciliation of net income available to common shareholders and the number of shares used in the calculation of basic and diluted earnings per common share. Basic earnings per share: Net income Less: Preferred stock dividends Net income after preferred stock dividends Less: Undistributed earnings allocated to participating securities Dividends paid on participating securities Net income available to common shareholders Weighted-average basic shares outstanding Basic earnings per share Diluted earnings per share: Net income available to common shareholders Total weighted-average basic shares outstanding Add dilutive stock warrants Total weighted-average diluted shares outstanding Diluted earnings per share Anti-dilutive participating securities 118 Years ended December 31, 2017 2016 2015 $ 76,512 $ 53,540 $ — 76,512 626 97 8 53,532 774 103 38,786 240 38,546 661 111 $ $ $ $ 75,789 25,394,079 2.98 75,789 $ $ $ 52,655 18,198,578 2.89 52,655 $ $ $ 37,774 16,974,484 2.23 37,774 25,394,079 18,198,578 16,974,484 106,070 86,646 84,595 25,500,149 18,285,224 17,059,079 2.97 $ 2.88 $ 123,564 92,196 2.21 58,726 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Note 2. Recent Accounting Pronouncements ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting was effective for the Company on January 1, 2017. ASU 2016-09 requires that all income tax effects related to vestings of share-based payment awards be reported in earnings as an expense (or benefit) to income tax expense. Previously, excess income tax benefits of a vested award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits recognized in earnings during the awards vesting period. The requirement to report those income tax effects in earnings has been applied to vestings occurring on or after January 1, 2017 and resulted in recording a $1,323 tax benefit for the year ended December 31, 2017. ASU 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. We have elected to apply the change in cash flow classification on a prospective basis. The impact of this change and that of the remaining provisions of ASU 2016-09 was not significant to our financial statements. ASU 2014-09, Revenue from Contracts with Customers (Topic 606), ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date: ASU 2014-09 amends existing guidance related to revenue from contracts with customers. The amendments state that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 affects entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards. The Company's revenue consists of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-9, and non-interest income. We finalized our analysis of the impact of ASU 2014-09 on the components of our non-interest income and determined that the adoption of this guidance will not result in any significant changes to our methodology of recognizing revenue or have a material impact on our internal controls over financial reporting. As required by ASU 2014-09, we will adopt the new standard effective January 1, 2018 and, at the time of this filing, we do not anticipate recording a cumulative effect adjustment to opening retained earnings or any presentation changes to the consolidated financial statements. The Company will provide the required revenue disclosures in our Form 10-Q for the quarter ended March 31, 2018. ASU 2016-01, Financial Instruments─Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale. Currently, the company values their financial instruments that are not measured at fair value in the financial statements using an entry price notion consistent with current guidance, and will be changing to the exit price notion in the first quarter of 2018 in compliance with this ASU. This update will be effective for the Company on January 1, 2018 and will not have a significant impact to the Company's consolidated financial statements and disclosures. ASU 2016-02, Leases (Topic 842), and ASU 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842. The amendments in ASU 2016-02, among other things, amended existing guidance that requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) A right-of- use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. The amendments will be effective for the Company on January 1, 2019 and is required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. The Company is currently evaluating the potential 119 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) effect of adopting this guidance on its consolidated financial statements and related disclosures. We expect our operating leases, as disclosed in Note 14, will be subject to the new standard resulting in recognized right-of-use assets and operating lease liabilities on the consolidated balance sheets upon adoption. Presentation of leases within the consolidated statements of income and consolidated statements of cash flows will be generally consistent with the current lease accounting guidance. ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this update replace the incurred loss model with the expected loss model. Among other things, these amendments require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. This update will be effective for the Company on January 1, 2020. The Company is currently evaluating the impact of the amendments on its consolidated financial statements and disclosures. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. The amendments in this update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount and the discount continues to be amortized to maturity. This update will be effective for the Company on January 1, 2019 and is not expected to have a significant impact to the Company's consolidated financial statements and disclosures. ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this update refine and expand hedge accounting for both financial and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. This update will be effective for the Company on January 1, 2019. The Company is evaluating the impact of the amendments on its consolidated financial statements and disclosures. ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act which was signed into law on December 22, 2017. The amendments also require certain disclosures about stranded tax effects. This update will be effective for all annual and interim periods beginning January 1, 2019, with early adoption permitted, and the guidance should be applied either in the period of adoption or the retrospectively to each period impacted by the change in the U.S federal corporate income tax rate in the Tax Cuts and Job Acts is recognized. The Company currently expects to early adopt the new guidance in the first quarter of 2018, which will result in a cumulative effect adjustment to the consolidated balance sheet as of January 1, 2018 to reclass approximately $132 thousand of tax expense from accumulated other comprehensive loss to retained earnings. Note 3. Restrictions on Cash and Due From Banks At December 31, 2017 and 2016, the Company had a reserve requirement of $36,321 and $0, respectively, with the Federal Reserve Bank. 120 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Note 4.

Loans, Net and Allowance for Loan Losses Loans, net at December 31, 2017 and 2016, consisted of the following: Commercial Real estate: Commercial Commercial construction, land and land development Residential Single family interim construction Agricultural Consumer Other Deferred loan fees Allowance for loan losses December 31, 2017 2016 $ 1,059,984 $ 630,805 3,369,892 744,868 892,293 289,680 82,583 34,639 304 6,474,243 (2,568) (39,402) 6,432,273 $ 2,459,221 531,481 634,545 235,475 53,548 27,530 166 4,572,771 (2,117) (31,591) 4,539,063 $ The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. The Company’s management examines current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. These cash flows, however, may not be as expected and the value of collateral securing the loans may fluctuate. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short term loans may be made on an unsecured basis. Additionally, our commercial loan portfolio includes loans made to customers in the energy industry, which is a complex, technical and cyclical industry. Experienced bankers with specialized energy lending experience originate our energy loans. Companies in this industry produce, extract, develop, exploit and explore for oil and natural gas. Loans are primarily collateralized with proven producing oil and gas reserves based on a technical evaluation of these reserves. At December 31, 2017 and 2016, there were approximately $90,323 and $115,311 respectively, of exploration and production (E&P) energy loans outstanding. Additionally, with the acquisition of Carlile, the Company acquired a mortgage warehouse purchase company, Goldome Financial, which provides a mortgage warehouse lending vehicle to third party mortgage bankers across a broad geographic scale. The mortgage loans are underwritten, in part, on approved investor takeout commitments. These loans have a very short duration ranging between 10 days and 15 days. In some cases, loans to larger mortgage originators may be financed for up to 60 days. These loans are reported as commercial loans since the loans are secured by notes receivable, not real estate. As of December 31, 2017, mortgage warehouse purchase loans outstanding totaled $164,694. During the fourth quarter of 2017, Goldome Financial was dissolved and the mortgage purchase program was merged into the Bank. Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors the diversification of the portfolio on a quarterly basis by type and geographic location. Management also tracks the level of owner occupied property versus non owner occupied property. At December 31, 2017, the portfolio consisted of approximately 34% of owner occupied property. 126 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Land and commercial land development loans are underwritten using feasibility studies, independent appraisal reviews and financial analysis of the developers or property owners. Generally, borrowers must have a proven track record of success. Commercial construction loans are generally based upon estimates of cost and value of the completed project. These estimates may not be accurate. Commercial construction loans often involve the disbursement of substantial funds with the repayment dependent on the success of the ultimate project. Sources of repayment for these loans may be pre-committed permanent financing or sale of the developed property. The loans in this portfolio are geographically diverse and due to the increased risk are monitored closely by management and the board of directors on a quarterly basis. Residential real estate and single family interim construction loans are underwritten primarily based on borrowers’ credit scores, documented income and minimum collateral values. Relatively small loan amounts are spread across many individual borrowers which minimizes risk in the residential portfolio. In addition, management evaluates trends in past dues and current economic factors on a regular basis. Agricultural loans are collateralized by real estate and/or agricultural-related assets. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Loan-to-value ratios on loans secured by farmland generally do not exceed 80% and have amortization periods limited to twenty years. Agricultural non-real estate loans are generally comprised of term loans to fund the purchase of equipment, livestock and seasonal operating lines to cash grain farmers to plant and harvest corn and soybeans. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary. Agricultural loans carry significant credit risks as they involve larger balances concentrated with single borrowers or groups of related borrowers. In addition, repayment of such loans depends on the successful operation or management of the farm property securing the loan or for which an operating loan is utilized. Farming operations may be affected by adverse weather conditions such as drought, hail or floods that can severely limit crop yields. Consumer loans represent less than 1% of the outstanding total loan portfolio. Collateral consists primarily of automobiles and other personal assets. Credit score analysis is used to supplement the underwriting process. Most of the Company’s lending activity occurs within the State of Texas, primarily in the north, central and southeast Texas regions. With the acquisition of Carlile as further explained in Note 20, Business Combination, the Company expanded into the State of Colorado, specifically along the Front Range area. As of December 31, 2017, loans in the Colorado region represented about 5.5% of the total portfolio. A large percentage of the Company’s portfolio consists of commercial and residential real estate loans. As of December 31, 2017 and 2016, there were no concentrations of loans related to a single industry in excess of 10% of total loans. The allowance for loan losses is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio. The allowance is derived from the following two components: 1) allowances established on individual impaired loans, which are based on a review of the individual characteristics of each loan, including the customer’s ability to repay the loan, the underlying collateral values, and the industry the customer operates, and 2) allowances based on actual historical loss experience for the last three years for similar types of loans in the Company’s loan portfolio adjusted for primarily changes in the lending policies and procedures; collection, charge-off and recovery practices; nature and volume of the loan portfolio; change in value of underlying collateral; volume and severity of nonperforming loans; existence and effect of any concentrations of credit and the level of such concentrations and current, national and local economic and business conditions. This second component also includes an unallocated allowance to cover uncertainties that could affect management’s estimate of probable losses. The unallocated allowance reflects the imprecision inherent in the underlying assumptions used in the methodologies for estimating this component. The Company’s management continually evaluates the allowance for loan losses determined from the allowances established on individual loans and the amounts determined from historical loss percentages adjusted for the qualitative factors above. Should any of the factors considered by management change, the Company’s estimate of loan losses could also change and would affect the level of future provision expense. While the calculation of the allowance for loan losses utilizes management’s best 127 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) judgment and all the information available, the adequacy of the allowance for loan losses is dependent on a variety of factors beyond the Company’s control, including, among other things, the performance of the entire loan portfolio, the economy, changes in interest rates and the view of regulatory authorities towards loan classifications. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses, and may require the Bank to make additions to the allowance based on their judgment about information available to them at the time of their examinations. Loans requiring an allocated loan loss provision are generally identified at the servicing officer level based on review of weekly past due reports and/or the loan officer’s communication with borrowers. In addition, past due loans are discussed at weekly officer loan committee meetings to determine if classification is warranted. The Company’s credit department has implemented an internal risk based loan review process to identity potential internally classified loans that supplements the annual independent external loan review. The external review generally covers all loans greater than $3.25 million annually. These reviews include analysis of borrower’s financial condition, payment histories and collateral values to determine if a loan should be internally classified. Generally, once classified, an impaired loan analysis is completed by the credit department to determine if the loan is impaired and the amount of allocated allowance required. The Texas and Colorado economies, specifically the Company’s lending area of north, central and southeast Texas and the Colorado Front Range area, have continued to expand at a moderate pace during 2017 due largely to improvement in manufacturing output, retail sales expansion, the energy sector and a strong service sector. The Texas economy is the second largest in the nation and remained strong during the last half of 2017, despite the impact of Hurricane Harvey during third quarter of 2017. The Hurricane devastated parts of the Gulf Coast and Houston with major flooding, destroying homes, business and infrastructure and causing refineries to shut down for days. The Bank initiated a Disaster Recovery Policy as a result of Harvey putting in place procedures and approval authorities for credit officers to provide relief for impacted borrowers. In the overall analysis of Harvey's impact on the Bank's loan portfolio, no significant additional risk has materialized and no additional reserves are warranted. Rebuilding efforts have supported the construction industry, generating rapid job creation and increased construction values. Overall, the forecast is strong with continued growth in the manufacturing and service sectors and a return to more normal activity in the energy sector. While the outlook remains optimistic, future concern to the economy continues to include energy price volatility and trade uncertainty, especially with Mexico. The risk of loss associated with all segments of the portfolio could increase due to this impact. 128 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) The economy and other risk factors are minimized by the Company’s underwriting standards which include the following principles: 1) financial strength of the borrower including strong earnings, high net worth, significant liquidity and acceptable debt to worth ratio, 2) managerial business competence, 3) ability to repay, 4) loan to value, 5) projected cash flow and 6) guarantor financial statements as applicable.

All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. Cash collections on nonaccrual loans are generally credited to the loan receivable balance, and no interest income is recognized on those loans until the principal balance has been collected. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. The Company has identified these loans through its normal loan review procedures. Impaired loans are measured based on 1) the present value of expected future cash flows discounted at the loans effective interest rate; 2) the loan's observable market price; or 3) the fair value of collateral if the loan is collateral dependent. Substantially all of the Company’s impaired loans are measured at the fair value of the collateral. In limited cases, the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent. All commercial, real estate, agricultural loans and troubled debt restructurings are considered for individual impairment analysis. Smaller balance consumer loans are collectively evaluated for impairment. 131 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Impaired loan information by loan class (excluding loans acquired with deteriorated credit quality) at December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 2015, is summarized as follows: Commercial Real Estate, Land and Land Development Residential Real Estate Single- Family Interim Construction Commercial Agricultural Consumer Other Total December 31, 2017 Recorded investment in impaired loans: Impaired loans with an allowance for loan losses Impaired loans with no allowance for loan losses Total Unpaid principal balance of impaired loans Allowance for loan losses on impaired loans December 31, 2016 Recorded investment in impaired loans: $ 9,255 $ 1,793 $ — $ — $ — $ 2 $ — $11,050 1,042 $ 10,297 $ 13,456 $ 3,500 $ $ $ 1,261 3,054 3,124 311 $ $ $ 1,727 1,727 1,818 $ $ — — — $ — $ 72 74 — 4,102 $ — $15,152 — $ — $ 197 $ — $18,595 — $ — $ — $ 2 $ — $ 3,813 Impaired loans with an allowance for loan losses Impaired loans with no allowance for loan losses Total $ $ 7,712 7,720 Unpaid principal balance of impaired loans $ 10,844 Allowance for loan losses on impaired loans For the year ended December 31, 2017 Average recorded investment in impaired loans Interest income recognized on impaired loans $ $ $ 3 8,524 8 For the year ended December 31, 2016 Average recorded investment in impaired loans $ 11,783 Interest income recognized on impaired loans For the year ended December 31, 2015 Average recorded investment in impaired loans Interest income recognized on impaired loans $ $ $ 58 4,951 189 8 $ 78 $ — $ 168 $ — $ 209 $ — $ 463 7,011 7,089 7,133 4 3,690 428 3,324 73 5,904 286 $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ 1,889 1,889 2,087 $ $ — $ 716 884 884 84 $ $ $ — — $ 70 279 — 17,398 $ — $17,861 — $ 291 $ — $21,239 — $ 94 $ — $ 185 2,431 58 2,773 97 3,220 181 $ $ $ $ $ $ 177 $ — $ 218 $ — $15,040 — $ — $ 5 $ — $ 499 177 $ 34 $ 118 $ — $18,209 — $ — $ — $ — $ 228 — $ — $ 34 10 $ $ 93 $ — $14,202 24 $ — $ 690 Certain impaired loans have adequate collateral and do not require a related allowance for loan loss. The Company will charge off that portion of any loan which management considers a loss. Commercial and real estate loans are generally considered for charge-off when exposure beyond collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition. The restructuring of a loan is considered a “troubled debt restructuring” if both 1) the borrower is experiencing financial difficulties and 2) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, extending amortization and other actions intended to minimize potential losses. 132 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) A “troubled debt restructured” loan is identified as impaired and measured for credit impairment as of each reporting period in accordance with the guidance in ASC 310-10-35. Modifications primarily relate to extending the amortization periods of the loans and interest rate concessions. The majority of these loans were identified as impaired prior to restructuring; therefore, the modifications did not materially impact the Company’s determination of the allowance for loan losses. The recorded investment in troubled debt restructurings, including those on nonaccrual, was $3,028 and $2,425 as of December 31, 2017 and 2016. Following is a summary of loans modified under troubled debt restructurings during the years ended December 31, 2017 and 2016: Commercial Real Estate, Land and Land Development Residential Real Estate Single-Family Interim Construction Commercial Agricultural Consumer Other Total Troubled debt restructurings during the year ended December 31, 2017 Number of contracts Pre-restructuring outstanding recorded investment Post-restructuring outstanding recorded investment Troubled debt restructurings during the year ended December 31, 2016 Number of contracts Pre-restructuring outstanding recorded investment Post-restructuring outstanding recorded investment $ $ $ $ 1 — 1 — — 1 — 3 873 $ — $ 465 $ — $ — $ 22 $ — $ 1,360 873 $ — $ 465 $ — $ — $ 22 $ — $ 1,360 1 — — — — 1 — 2 24 $ — $ — $ — $ — $ 209 $ — $ 233 24 $ — $ — $ — $ — $ 209 $ — $ 233 At December 31, 2017 and 2016, there were no loans modified under troubled debt restructurings during the previous twelve month period that subsequently defaulted during the years ended December 31, 2017 and 2016. At December 31, 2017 and 2016, the Company had no commitments to lend additional funds to any borrowers with loans whose terms have been modified under troubled debt restructurings. 133 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. The following table presents information regarding the aging of past due loans by loan class as of December 31, 2017 and 2016: December 31, 2017 Commercial Commercial real estate, land and land development Residential real estate Single-family interim construction Agricultural Consumer Other Acquired with deteriorated credit quality December 31, 2016 Commercial Commercial real estate, land and land development Residential real estate Single-family interim construction $ $ Agricultural Consumer Other Acquired with deteriorated credit quality Loans 30-89 Days Past Due Loans 90 or More Past Due Total Past Due Loans Current Loans Total Loans $ 730 $ 10,300 $ 11,030 $ 1,036,668 $ 1,047,698 4,083 6,269 1,436 — 373 — 12,891 2,748 15,639 226 151 846 1,062 10 154 — 2,449 181 $ $ 1,944 138 — — 47 — 12,429 4,013 16,442 7,711 6,752 561 — — 52 — 15,076 910 $ $ 6,027 6,407 1,436 — 420 — 4,036,359 4,042,386 882,612 288,244 78,646 34,198 304 889,019 289,680 78,646 34,618 304 25,320 6,357,031 6,382,351 6,761 32,081 85,131 $ 6,442,162 91,892 $ 6,474,243 7,937 $ 620,448 $ 628,385 6,903 1,407 1,062 10 206 — 2,953,519 2,960,422 631,171 234,413 53,538 27,313 166 632,578 235,475 53,548 27,519 166 17,525 4,520,568 4,538,093 1,091 33,587 $ 4,554,155 34,678 $ 4,572,771 $ 2,630 $ 15,986 $ 18,616 The Company’s internal classified report is segregated into the following categories: 1) Pass/Watch, 2) Special Mention, 3) Substandard and 4) Doubtful. The loans placed in the Pass/Watch category reflect the Company’s opinion that the loans reflect potential weakness which requires monitoring on a more frequent basis. The loans in the Special Mention category reflect the Company’s opinion that the credit contains weaknesses which represent a greater degree of risk and warrant extra attention. These loans are reviewed monthly by officers and senior management to determine if a change in category is warranted. The loans placed in the Substandard category are considered to be potentially inadequately protected by the current debt service capacity of the borrower and/or the pledged collateral. These credits, even if apparently protected by collateral value, have shown weakness related to adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and interest. There is possibility that some future loss could be sustained by the Company if such weakness is not corrected. The Doubtful category includes loans that are in default or principal exposure is probable. Substandard and Doubtful loans are individually evaluated to determine if they should be classified as impaired and an allowance is allocated if deemed necessary under ASC 310-10. The loans that are not impaired are included with the remaining “pass” credits in determining the portion of the allowance for loan loss based on historical loss experience and other qualitative factors. The portfolio is segmented into categories including: commercial loans, consumer loans, commercial real estate loans, residential real estate loans and agricultural loans. The adjusted historical loss percentage is applied to each category. Each category is then added together to determine the allowance allocated under ASC 450-20. 134 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) A summary of loans by credit quality indicator by class as of December 31, 2017 and 2016, is as follows: December 31, 2017 Commercial Commercial real estate, construction, land and land development Residential real estate Single-family interim construction Agricultural Consumer Other December 31, 2016 Commercial Commercial real estate, construction, land and land development Residential real estate Single-family interim construction Agricultural Consumer Other Pass Pass/ Watch Special Mention Substandard Doubtful Total $ 989,953 $ 35,105 $ 3,737 $ 31,189 $ — $ 1,059,984 4,040,385 46,288 11,915 883,653 288,020 59,392 34,510 2,722 1,660 5,762 25 462 — 13,802 4 304 $ 6,296,217 — $ 91,562 — $ 29,920 $ 555,342 $ 31,954 $ 16,734 2,972,732 629,081 233,800 52,724 27,215 5,426 1,897 791 569 12 5,148 370 — 255 3 166 $ 4,471,060 — $ 40,649 — $ 22,510 $ $ 16,172 5,456 — 3,627 100 — 56,544 26,775 7,396 3,197 884 — 300 — $ $ $ 38,552 $ — 4,114,760 — — — — 892,293 289,680 82,583 34,639 — 304 — $ 6,474,243 — $ 630,805 — 2,990,702 — — — — 634,545 235,475 53,548 27,530 — 166 — $ 4,572,771 The Company has acquired certain loans which experienced credit deterioration since origination (purchase credit impaired (PCI) loans).

Junior Subordinated Debentures The Company has formed or acquired seven statutory business trusts under the laws of the State of Delaware for the purpose of issuing trust preferred securities. The statutory business trusts formed or acquired by the Company (the "Trusts") have each issued capital and common securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the "Debentures") issued by the Company. The interest rate payable on, and the payment terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of capital and common securities issued by the Trusts. The Debentures are subordinated and junior in right of payment to all present and future senior indebtedness. The Company has fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the capital and common securities. Except under certain circumstances, the common securities issued to the Company by the trusts possess sole voting rights with respect to matters involving those entities. Under certain circumstances, the Company may, from time to time, defer the debentures' interest payments, which would result in a deferral of distribution payments on the related trust preferred securities and, with certain exceptions, prevent the Company from declaring or paying cash distributions on the Company's common stock and any other future debt ranking equally with or junior to the debentures. As of December 31, 2017 and 2016, the carrying amount of debentures outstanding totaled $27,654 and $18,147, respectively. As a result of the Carlile acquisition during 2017 (see Note 20), the Company assumed subordinated obligations for two statutory Trusts. At acquisition date, the total debt for these two Trusts was recorded at fair value with a recorded discount totaling $4,045, which will be amortized back to par value over the estimated lives of the instruments.

Income Taxes Income tax expense for the years ended December 31, 2017, 2016 and 2015 was as follows: Current income tax expense Deferred income tax expense (benefit) Deferred income tax expense related to remeasurement of deferred taxes Income tax expense, as reported Years Ended December 31, 2017 2016 2015 $ $ 28,121 11,526 5,528 $ 28,440 $ (1,849) — 22,946 (3,935) — 45,175 $ 26,591 $ 19,011 140 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) A reconciliation between reported income tax expense and the amounts computed by applying the U.S. federal statutory income tax rate of 35% to income before income taxes for the years ended December 31, 2017, 2016 and 2015 is presented below: Income tax expense computed at the statutory rate Tax-exempt interest income from municipal securities Tax-exempt loan income Bank owned life insurance income Non-deductible acquisition expenses State taxes, net of federal benefit Net tax benefit from stock based compensation Deferred tax adjustment related to reduction in U.S. Federal statutory income tax rate Other Years Ended December 31, 2017 2016 2015 $ 42,590 $ 28,046 $ 20,229 (1,357) (435) (962) 491 241 (1,323) 5,528 402 (619) (436) (472) — — — — 72 (624) (398) (377) 108 — — — 73 $ 45,175 $ 26,591 $ 19,011 The Tax Cuts and Jobs Act, which was enacted on December 22, 2017, made significant changes to the U.S. tax law, including the reduction of the corporate income tax rate from 35% to 21%. As a result of enactment, we remeasured our deferred tax assets and liabilities based upon the newly enacted U.S. statutory federal income tax rate of 21%, which is the tax rate at which these assets and liabilities are expected to reverse in the future and, as noted above, recognized a tax expense related to the remeasurement of $5,528. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. The Company has completed its accounting under ASC 740 for all material deferred tax assets and liabilities. Provisional amounts have been recorded for certain immaterial items, such as Schedules K-1 from partnership investments and state apportionment. Material adjustments to provisional amounts are not anticipated during the SAB 118 measurement period. 141 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Components of deferred tax assets and liabilities are presented in the table below. As a result of the Tax Cuts and Jobs Act, deferred taxes as of December 31, 2017 are based on the newly enacted U.S. statutory federal income tax rate of 21%. Deferred taxes of December 31, 2016 are based on the previously enacted U.S. statutory federal income tax rate of 35%. Deferred tax assets: Allowance for loan losses NOL and tax credit carryforwards from acquisitions Net unrealized loss on available for sale securities Acquired loan fair market value adjustments Restricted stock Reserve for bonuses Deferred loan fees Securities Start up costs Other real estate owned Unearned bankcard income Deferred compensation Noncompete agreements Nonaccrual loans Other Deferred tax liabilities: Premises and equipment Core deposit intangibles Acquired junior subordinated debentures fair value adjustment Securities FHLB stock Acquired tax accounting method changes Prepaids Acquired tax goodwill Other Net deferred tax asset December 31, 2017 2016 $ 8,365 $ 11,057 6,791 349 5,214 791 479 545 265 281 402 244 492 526 414 310 25,468 (5,128) (9,181) (818) — (204) — (153) (111) (110) 383 912 2,740 1,363 1,946 741 — 249 18 495 — — 70 248 20,222 (5,107) (4,953) — (218) (157) (156) — — — $ (15,705) 9,763 $ (10,591) 9,631 At December 31, 2017, the Company had federal net operating loss carryforwards of approximately $26,795 which expire in various years from 2022 to 2032, federal tax credit carryovers of approximately $132 which will never expire and state net operating loss carryforwards of approximately $28,203 which expire in various years from 2028 to 2036. Deferred tax assets are recognized for net operating losses because the benefit is more likely than not to be realized. No valuation allowance for deferred tax assets was recorded at December 31, 2017 or 2016 as management believes it is more likely than not that all of the deferred tax assets will be realized. The Company does not have any material uncertain tax positions and does not have any interest and penalties recorded in the income statement for the years ended December 31, 2017, 2016 and 2015. The Company files a consolidated income tax return in the US federal tax jurisdiction. The Company is no longer subject to examination by the US federal tax jurisdiction for years prior to 2014. 142 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Note 14. Commitments and Contingencies Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. The commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of this instrument. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. At December 31, 2017 and 2016, the approximate amounts of these financial instruments were as follows: Commitments to extend credit Standby letters of credit December 31, 2017 1,286,704 10,532 1,297,236 $ $ 2016 865,668 10,562 876,230 $ $ Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, farm crops, property, plant and equipment and income-producing commercial properties. Letters of credit are written conditional commitments used by the Company to guarantee the performance of a customer to a third party. The Company’s policies generally require that letter of credit arrangements contain security and debt covenants similar to those contained in loan arrangements. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the table above. If the commitment is funded, the Company would be entitled to seek recovery from the customer. As of December 31, 2017 and 2016, no amounts have been recorded as liabilities for the Company’s potential obligations under these guarantees. Litigation The Company is involved in certain legal actions arising from normal business activities. Management believes that the outcome of such proceedings will not materially affect the financial position, results of operations or cash flows of the Company. A legal proceeding that the Company believes could become material is described below. Independent Bank is a party to a legal proceeding inherited by Independent Bank in connection with its acquisition of BOH Holdings, Inc. and its subsidiary, Bank of Houston (BOH). The plaintiffs in the case are alleging that Independent Bank aided and abetted or participated in a fraudulent scheme. Independent Bank is pursuing insurance coverage for these claims, including reimbursement for defense costs. The Company believes the claims made in this lawsuit are without merit and is vigorously defending the lawsuit. The Company is unable to predict when the matter will be resolved, the ultimate outcome or potential costs or damages to be incurred. Please see Part I, Item 3. for more details on this lawsuit. Lease Commitments The Company leases certain branch facilities and other facilities. Rent expense related to these leases amounted to $3,073, $2,114 and $1,762 for the years ended December 31, 2017, 2016 and 2015, respectively. 143 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) At December 31, 2017, minimum future rental payments due under noncancelable lease commitments were as follows: First year Second year Third year Fourth year Fifth year Thereafter $ $ 2,794 2,324 2,105 1,947 1,357 4,707 15,234 Note 15. Related Party Transactions In the ordinary course of business, the Company has and expects to continue to have transactions, including loans to its officers, directors and their affiliates. In the opinion of management, such transactions are on the same terms as those prevailing at the time for comparable transactions with unaffiliated persons. Loan activity for officers, directors and their affiliates for the year ended December 31, 2017 is as follows: Balance at beginning of year New loans Repayments Changes in affiliated persons Balance at end of year See also Note 11 for related party borrowings. Note 16. Employee Benefit Plans $ $ 58,863 18,941 (15,985) 2,097 63,916 The Company has a 401(k) profit sharing plan (Plan) which covers employees over the age of eighteen who have completed ninety days of credited service, as defined by the Plan. The Plan provides for “before tax” employee contributions through salary reduction contributions under Section 401(k) of the Internal Revenue Code. A participant may choose a salary reduction not to exceed the dollar limit set by law each year ($18 in 2017). Contributions by the Company and by participants are immediately fully vested. The Plan provides for the Company to make 401(k) matching contributions ranging from 50% to 100% depending upon the employee's years of service, but limited to 6% of the participant's eligible salary. The Plan also provides for the Company to make additional discretionary contributions to the Plan. The Company made contributions of approximately $2,070, $1,393 and $1,208 for the years ended December 31, 2017, 2016 and 2015, respectively. Note 17. Fair Value Measurements The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. 144 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. The following table represents assets and liabilities reported on the consolidated balance sheets at their fair value on a recurring basis as of December 31, 2017 and 2016 by level within the ASC Topic 820 fair value measurement hierarchy: Fair Value Measurements at Reporting Date Using Assets/ Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2017 Measured on a recurring basis: Assets: Securities available for sale: U.S. treasuries Government agency securities Obligations of state and municipal subdivisions Residential pass-through securities guaranteed by FNMA, GNMA, FHLMC, FHR and GNR Other securities December 31, 2016 Measured on a recurring basis: Assets: $ 37,154 $ — $ 37,154 $ 211,509 229,613 274,377 10,349 — — — 10,349 211,509 229,613 274,377 — Securities available for sale: U.S. treasuries Government agency securities Obligations of state and municipal subdivisions Residential pass-through securities guaranteed by FNMA, GNMA and FHLMC $ 3,147 $ — $ 3,147 $ 122,267 87,256 103,765 — — — 122,267 87,256 103,765 — — — — — — — — — There were no transfers between level categorizations and no changes in valuation methodologies for the years presented. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Securities classified as available for sale are reported at fair value utilizing Level 1 and Level 2 inputs. Securities are classified within Level 1 when quoted market prices are available in an active market. Inputs include securities that have quoted prices in active markets for identical assets. For securities utilizing Level 2 inputs, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. 145 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) In accordance with ASC Topic 820, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table presents the assets carried on the consolidated balance sheet by caption and by level in the fair value hierarchy at December 31, 2017 and 2016, for which a nonrecurring change in fair value has been recorded: Fair Value Measurements at Reporting Date Using Assets/ Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Period Ended Total Losses December 31, 2017 Measured on a nonrecurring basis: Assets: Impaired loans $ 7,237 $ Other real estate owned 1,726 — $ — — $ — 7,237 $ 1,726 3,719 375 December 31, 2016 Measured on a nonrecurring basis: Assets: Impaired loans $ Other real estate owned $ 968 340 — $ — — $ — $ 968 340 708 52 Impaired loans (loans which are not expected to repay all principal and interest amounts due in accordance with the original contractual terms) are measured at an observable market price (if available) or at the fair value of the loan’s collateral (if collateral dependent). Fair value of the loan’s collateral is determined by appraisals or independent valuation which is then adjusted for the estimated costs related to liquidation of the collateral. Management’s ongoing review of appraisal information may result in additional discounts or adjustments to valuation based upon more recent market sales activity or more current appraisal information derived from properties of similar type and/or locale. Therefore, the Company has categorized its impaired loans as Level 3. Other real estate is measured at fair value on a nonrecurring basis (upon initial recognition or subsequent impairment). Other real estate owned is classified within Level 3 of the valuation hierarchy. When transferred from the loan portfolio, other real estate owned is adjusted to fair value less estimated selling costs and is subsequently carried at the lower of carrying value or fair value less estimated selling costs. The fair value is determined using an external appraisal process, discounted based on internal criteria. In addition, mortgage loans held for sale are required to be measured at the lower of cost or fair value. The fair value of mortgage loans held for sale is based upon binding quotes or bids from third party investors. As of December 31, 2017 and 2016, all mortgage loans held for sale were recorded at cost. 146 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) The methods and assumptions used by the Company in estimating fair values of financial instruments as disclosed herein in accordance with ASC Topic 825, Financial Instruments, other than for those measured at fair value on a recurring and nonrecurring basis discussed above, are as follows: Cash and cash equivalents: The carrying amounts of cash and cash equivalents approximate their fair value. Certificates of deposit held in other banks: The fair value of certificates of deposit held in other banks is based upon current rates in the market. Loans held for sale: The fair value of loans held for sale is determined based upon commitments on hand from investors. Loans: For variable-rate loans that reprice frequently and have no significant changes in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (for example, one-to-four family residential), commercial real estate and commercial loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Federal Home Loan Bank of Dallas and other restricted stock: The carrying value of restricted securities such as stock in the Federal Home Loan Bank of Dallas and Independent Bankers Financial Corporation approximates fair value. Deposits: The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is their carrying amounts). The carrying amounts of variable-rate certificates of deposit (CDs) approximate their fair values at the reporting date. Fair values for fixed-rate CDs are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Federal Home Loan Bank advances, line of credit and federal funds purchased: The fair value of advances maturing within 90 days approximates carrying value. Fair value of other advances is based on the Company’s current borrowing rate for similar arrangements. Repurchase agreements and other borrowings: The carrying value of repurchase agreements approximates fair value due to the short term nature. The fair values of privately issued subordinated debentures are based upon prevailing rates on similar debt in the market place. The subordinated debentures that are publicly traded are valued based on indicative bid prices based upon market pricing observations in the current market. Junior subordinated debentures: The fair value of junior subordinated debentures is estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Accrued interest: The carrying amounts of accrued interest approximate their fair values. Off-balance sheet instruments: Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of commitments is not material. 147 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) The carrying amount, estimated fair value and the level of the fair value hierarchy of the Company’s financial instruments were as follows at December 31, 2017 and 2016: Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Carrying Amount Estimated Fair Value December 31, 2017 Financial assets: Cash and cash equivalents $ 431,102 $ 431,102 $ 431,102 $ — $ 6,343,179 7,237 Certificates of deposit held in other banks Securities available for sale Loans held for sale Loans, net FHLB of Dallas stock and other restricted stock Accrued interest receivable Financial liabilities: Deposits Accrued interest payable FHLB advances Other borrowings Junior subordinated debentures Off-balance sheet assets (liabilities): Commitments to extend credit Standby letters of credit December 31, 2016 Financial assets: 12,985 763,002 39,202 13,049 763,002 40,436 6,432,273 6,350,416 29,184 20,835 29,184 20,835 6,632,822 6,637,813 4,654 530,667 136,911 27,654 — — 4,654 526,514 141,650 20,008 — — — 10,349 — — — — — — — — — — — 13,049 752,653 40,436 29,184 20,835 6,637,813 4,654 526,514 141,650 20,008 — — Cash and cash equivalents $ 505,027 $ 505,027 $ 505,027 $ — $ Certificates of deposit held in other banks Securities available for sale Loans held for sale Loans, net FHLB of Dallas stock and other restricted stock Accrued interest receivable Financial liabilities: Deposits Accrued interest payable FHLB advances Other borrowings Junior subordinated debentures Off-balance sheet assets (liabilities): Commitments to extend credit Standby letters of credit — — — — — — — — — — — — — 2,733 316,435 9,795 4,532,086 26,536 12,331 4,581,866 4,020 459,436 110,000 18,131 — — 2,707 316,435 9,795 2,733 316,435 9,795 4,539,063 4,532,364 26,536 12,331 26,536 12,331 4,577,109 4,581,866 4,020 459,436 110,000 18,131 — — 4,020 460,746 107,299 18,147 — — 148 — — — — — — — — — — — — — — — — — 278 — — — — — — — — — Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Note 18. Stock Awards and Stock Warrants The Company grants common stock awards to certain employees of the Company. The common stock awards issued prior to 2013 vest five years from the date the award was granted and the related compensation expense is recognized over the vesting period. In connection with the Company's initial public offering in April 2013, the Board of Directors adopted a new 2013 Equity Incentive Plan. Under this plan, the Compensation Committee may grant awards in the form of restricted stock, restricted stock rights, restricted stock units, qualified and nonqualified stock options, performance-based share awards and other equity-based awards. The Plan reserved 800,000 shares of common stock to be awarded by the Company’s compensation committee. As of December 31, 2017, there were 207,975 shares remaining available for grant for future awards. The shares currently issued under the 2013 Plan are restricted and will vest evenly over the required employment period, generally ranging from three to five years. Shares granted under a previous plan prior to 2012 and those in and subsequent to 2013 under the 2013 Equity Incentive Plan were issued at the date of grant and receive dividends. Shares issued under a revised plan in 2012 are not outstanding shares of the Company until they vest and do not receive dividends. During the year ended December 31, 2017, 25,760 shares that were issued under the 2012 Plan vested during the period. As of December 31, 2017, all stock awards issued under expired plans prior to 2013 are fully vested. The following table summarizes the activity in nonvested shares for the years ended December 31, 2017 and 2016: Nonvested shares, December 31, 2016 Granted during the period Vested during the period Forfeited during the period Nonvested shares, December 31, 2017 Nonvested shares, December 31, 2015 Granted during the period Vested during the period Forfeited during the period Nonvested shares, December 31, 2016 Number of Shares Weighted Average Grant Date Fair Value 280,524 104,962 (140,887) (2,543) 242,056 373,572 88,220 (153,766) (27,502) 280,524 $ $ $ $ 36.88 61.89 34.18 48.29 49.17 40.29 31.92 36.42 31.75 36.88 Compensation expense related to these awards is recorded based on the fair value of the award at the date of grant and totaled $4,688, $5,431 and $4,314 for the years ended December 31, 2017, 2016 and 2015, respectively. Compensation expense is recorded in salaries and employee benefits in the accompanying consolidated statements of income. At December 31, 2017, future compensation expense is estimated to be $8,136 and will be recognized over a remaining weighted average period of 2.63 years. The fair value of common stock awards that vested during the years ended December 31, 2017, 2016 and 2015 was $8,597, $5,208 and $3,300, respectively. The Company has recorded $1,323 in excess tax benefits on vested restricted stock to income tax expense for the year ended December 31, 2017, as a result of adopting ASU 2016-09 as explained in Note 2. The Company recorded $(137) and $(72) to additional paid in capital, which represents the income tax deficiency recognized on the vested shares for the years ended December 31, 2016 and 2015, respectively. There were no modifications of stock agreements during 2017, 2016 and 2015 that resulted in significant additional incremental compensation costs. At December 31, 2017, the future vesting schedule of the nonvested shares is as follows: First year Second year Third year Fourth year Fifth year Total nonvested shares 149 113,247 75,390 30,468 13,297 9,654 242,056 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) The Company has warrants outstanding representing the right to purchase 147,341 shares of Company stock at $17.19 per share to certain Company directors and shareholders. The warrants were issued in return for the shareholders' agreement to repurchase the subordinated debt outstanding to an unaffiliated bank in the event of Company default. The warrants were recorded as equity awards at fair value and were being amortized over the term of the debt. The subordinated debt was paid off by the Company in 2013. The warrants expire in December 2018. During the year ended December 31, 2017, warrants to purchase 3,203 shares of common stock were exercised and have been issued by the Company. There were no warrants exercised during 2016. Note 19. Regulatory Matters Under banking law, there are legal restrictions limiting the amount of dividends the Bank can declare. Approval of the regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. For state banks, subject to regulatory capital requirements, payment of dividends is generally allowed to the extent of net profits. The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The Company is subject to the Basel III regulatory capital framework (the "Basel III Capital Rules"). Starting in January 2016, the implementation of the capital conservation buffer became effective for the Company starting at the 0.625% level and increasing 0.625% each year thereafter, until it reaches 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress and requires increased capital levels for the purpose of capital distributions and other payments. Failure to meet the full amount of the buffer will result in restrictions on the Company's ability to make capital distributions, including dividend payments and stock repurchases and to pay discretionary bonuses to executive officers. When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company and Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus the 2.5% capital conservation buffer (7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the 2.5% capital conservation buffer (8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the 2.5% capital conservation buffer (10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Common Equity Tier 1 ("CET1") and Tier 1 capital (as defined in the regulations) to risk weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2017 and 2016, the Company and the Bank meet all capital adequacy requirements to which they are subject, including the capital buffer requirement. As of December 31, 2017 and 2016, the Bank’s capital ratios exceeded those levels necessary to be categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized," the Bank must maintain minimum total risk based, CET1, Tier 1 risk based and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the Bank’s category. 150 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) The actual capital amounts and ratios of the Company and Bank as of December 31, 2017 and 2016, are presented in the following table: Actual Amount Ratio Minimum for Capital Adequacy Purposes Ratio Amount To Be Well Capitalized Under Prompt Corrective Action Provisions Ratio Amount December 31, 2017 Total capital to risk weighted assets: Consolidated Bank $ 897,760 867,082 12.56% $ 572,025 571,142 12.15 8.00% 8.00 N/A $ 713,928 N/A 10.00% Tier 1 capital to risk weighted assets: Consolidated Bank Common equity tier 1 to risk weighted assets: Consolidated Bank Tier 1 capital to average assets: Consolidated Bank December 31, 2016 Total capital to risk weighted assets: 718,358 827,680 687,006 827,680 718,358 827,680 10.05 11.59 9.61 11.59 8.92 10.30 429,019 428,357 321,764 321,268 322,124 321,384 6.00 6.00 4.50 4.50 4.00 4.00 N/A 571,142 N/A 464,053 N/A 401,730 N/A 8.00 N/A 6.50 N/A 5.00 Consolidated Bank $ 568,808 558,551 11.38% $ 399,698 399,497 11.19 8.00% 8.00 N/A $ 499,371 N/A 10.00% Tier 1 capital to risk weighted assets: Consolidated Bank Common equity tier 1 to risk weighted assets: Consolidated Bank Tier 1 capital to average assets: Consolidated Bank 427,217 526,960 409,617 526,960 427,217 526,960 8.55 10.55 8.20 10.55 7.82 9.65 299,774 299,623 224,830 224,717 218,612 218,517 6.00 6.00 4.50 4.50 4.00 4.00 N/A 399,497 N/A 324,591 N/A 273,146 N/A 8.00 N/A 6.50 N/A 5.00 Note 20. Business Combinations Integrity Bancshares, Inc. On November 28, 2017, the Company announced that it entered into a definitive agreement to acquire Integrity Bancshares, Inc. and its subsidiary, Integrity Bank, SSB, Houston, Texas (Integrity). Under the terms of the agreement, the Company will issue 2,072,131 shares of the Company's common stock and pay cash in the aggregate amount of $31.6 million to the shareholders and option holders of Integrity. The merger has been approved by the Boards of Directors of both companies and is expected to close during the second quarter of 2018, although delays may occur. The transaction is subject to certain conditions, including the approval by shareholders of Independent Bank Group, Integrity Bancshares and customary regulatory approvals. 151 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Carlile Bancshares, Inc. On April 1, 2017, the Company acquired 100% of the outstanding stock of Carlile. This transaction resulted in 24 additional branches in the DFW Metroplex and Austin area as well as 18 branches in Colorado. The Company issued 8,804,699 shares of Company stock and paid $17,773 in cash for the outstanding shares of Carlile common stock. During the fourth quarter of 2017, the Company sold nine of the acquired Colorado branches as part of the Northstar branch integration process (see Note 21). The Company has recognized total goodwill of $363,139 which is calculated as the excess of both the consideration exchanged and liabilities assumed compared to the fair market value of identifiable assets acquired. The fair value of the consideration exchanged related to the Company's stock was calculated based upon the closing market price of the Company's stock as of March 31, 2017. The goodwill in this acquisition resulted from a combination of expected synergies and entrance into desirable Texas and Colorado markets. None of the goodwill recognized is expected to be deductible for income tax purposes. The Company has incurred expenses related to the acquisition of approximately $15,648 for the year ended December 31, 2017 which are included in noninterest expense in the consolidated statements of income. The Company incurred expenses of $659 during the year ended December 31, 2016. In addition, as of December 31, 2017, the Company paid offering costs totaling $942 which were recorded as a reduction to stock issuance proceeds through additional paid in capital. Fair values of the assets acquired and liabilities assumed in this transaction as of the closing date and subsequent measurement period adjustments are as follows: Assets of acquired bank: Cash and cash equivalents Certificates of deposit held in other banks Securities available for sale Loans Premises and equipment Other real estate owned Goodwill Core deposit intangible Other assets Total assets acquired Liabilities of acquired bank: Deposits Junior subordinated debentures Other liabilities Total liabilities assumed Common stock issued at $64.30 per share Cash paid Initially Recorded at Acquisition Date Measurement Period Adjustments Adjusted Values $ 148,444 $ 11,025 336,540 1,384,041 63,561 9,976 362,993 36,717 89,624 — $ — — 169 (395) 1,236 146 — 78 148,444 11,025 336,540 1,384,210 63,166 11,212 363,139 36,717 89,702 $ $ $ $ $ 2,442,921 $ 1,234 $ 2,444,155 1,825,181 $ — $ 1,825,181 9,359 24,466 1,859,006 566,142 17,773 $ $ $ — 1,234 1,234 $ — $ — $ 9,359 25,700 1,860,240 566,142 17,773 The nature of the measurement period adjustments noted in the table above was a result of information obtained subsequent to our initial reporting of provisional fair values but prior to finalizing our fair values as of December 31, 2017. Such information was determined to be a condition in existence as of acquisition date. The income effects resulting from the recorded measurement period adjustments during the year ending December 31, 2017 are immaterial for separate disclosure. 152 Independent Bank Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements (Dollars in thousands, except for share and per share information) Non-credit impaired loans had a fair value of $1,298,442 at acquisition date and contractual balance of $1,309,360. As of acquisition date, the Company expects that an insignificant amount of the contractual balance of these loans will be uncollectible. The difference of $10,918 will be recognized into interest income as an adjustment to yield over the life of the loans. The following table presents pro forma information as if the Carlile acquisition was completed as of January 1, 2016. The pro forma results combine the historical results of Carlile into the Company's consolidated statement of income including the impact of certain purchase accounting adjustments including loan discount accretion, intangible assets amortization, and junior subordinated debentures discount amortization. The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the results that would have been obtained had the acquisition actually occurred on January 1 of each year.

Revenues and earnings of the acquired company since the acquisition date have not been disclosed as Carlile was merged into the Company and separate financial information is not readily available.
