Forward Looking Statements This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. The words “expect,” “anticipate,” “intend,” “may,” “should,” “plan,” “believe,” “seek,” “estimate” and similar expressions are intended to identify such forward-looking statements, but other statements not based on historical information may also be considered forward-looking statements. These statements should be considered subject to various risks and uncertainties, and are made based upon management’s belief as well as assumptions made by, and information currently available to, management pursuant to “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The actual results of Pinnacle Financial Partners, Inc. (“Pinnacle Financial” or the “Company”) may differ materially from the results anticipated in forward-looking statements due to a variety of factors including, but not limited to: (i) deterioration in the financial condition of borrowers resulting in significant increases in loan losses and provisions for those losses; (ii) the ability to grow and retain low-cost core deposits and retain large, uninsured deposits; (iii) the inability of Pinnacle Financial, or entities in which it has significant investments, like BHG, to maintain the historical growth rate of its, or such entities', loan portfolio; (iv) changes in loan underwriting, credit review or loss reserve policies associated with economic conditions, examination conclusions, or regulatory developments; (v) effectiveness of Pinnacle Financial's asset management activities in improving, resolving or liquidating lower-quality assets; (vi) the impact of competition with other financial institutions, including pricing pressures and the resulting impact on Pinnacle Financial’s results, including as a result of compression to net interest margin; (vii) adverse conditions in the national or local economies including in Pinnacle Financial's markets throughout Tennessee, North Carolina, South Carolina and Virginia, particularly in commercial and residential real estate markets; (viii) fluctuations or differences in interest rates on loans or deposits from those that Pinnacle Financial is modeling or anticipating or that affect the yield curve; (ix) the results of regulatory examinations; (x) Pinnacle Financial’s ability to identify potential candidates for, consummate, and achieve synergies resulting from, potential future acquisitions and difficulties and delays in integrating acquired businesses or fully realizing cost savings and other benefits from acquisitions; (xi) risks of expansion into new geographic or product markets; (xii) any matter that would cause Pinnacle Financial to conclude that there was impairment of any asset, including intangible assets; (xiii) reduced ability to attract additional financial advisors (or failure of such advisors to cause their clients to switch to Pinnacle Bank), to retain financial advisors (including as a result of the competitive environment for associates) or otherwise to attract customers from other financial institutions; (xiv) the ability of Pinnacle Financial to implement its branch consolidation strategy on the timelines, and at the costs, presently contemplated; (xv) deterioration in the valuation of other real estate owned and increased expenses associated therewith; (xvi) inability to comply with regulatory capital requirements, including those resulting from changes to capital calculation methodologies, required capital maintenance levels or regulatory requests or directives, particularly if Pinnacle Financial's level of applicable commercial real estate loans were to exceed percentage levels of total capital in guidelines recommended by its regulators; (xvii) approval of the declaration of any dividend by Pinnacle Financial's board of directors; (xviii) the vulnerability of Pinnacle Bank's network and online banking portals, and the systems of parties with whom Pinnacle Financial contracts, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches; (xix) the possibility of increased compliance and operational costs as a result of increased regulatory oversight (including by the Consumer Financial Protection Bureau), including oversight of companies in which Pinnacle Financial or Pinnacle Bank have significant investments, like BHG, and the development of additional banking products for Pinnacle Bank's corporate and consumer clients; (xx) the risks associated with Pinnacle Financial and Pinnacle Bank being a minority investor in BHG, including the risk that the owners of a majority of the equity interests in BHG decide to sell the company if not prohibited from doing so by Pinnacle Financial or Pinnacle Bank; (xxi) changes in state and federal legislation, regulations or policies applicable to banks and other financial service providers, like BHG, including regulatory or legislative developments; (xxii) risks associated with the possible shutdown of the United States Federal government, including the adverse effects on the national or local economies and adverse effects resulting from a shutdown of the U.S. Small Business Administration’s SBA loan program; (xxiii) the availability of and access to capital; (xxiv) adverse results (including costs, fines, reputational harm, inability to obtain necessary approvals and/or other negative effects) from current or future litigation, regulatory examinations or other legal and/or regulatory actions; (xxv) general competitive, economic, political and market conditions; and (xxvi) and other factors and information contained in Pinnacle Financial’s reports and filings with the SEC, including those described in “Item 1A Risk Factors” of Pinnacle Financial’s quarterly report on Form 10-Q for the quarter ended June 30, 2019. Many of these risks factors are beyond Pinnacle Financial’s ability to control or predict, and you are cautioned not to put undue reliance on the forward-looking statements appearing in this presentation. Forward-looking statements represent Pinnacle Financial’s estimates and assumptions only as of the date that they were made. Pinnacle Financial does not intend to update or reissue any forward-looking statements contained in this presentation as a result of new information or other circumstances that may become known to Pinnacle Financial. Safe Harbor Statements

Safe Harbor Statements Non-GAAP Financial Matters This presentation contains certain non-GAAP financial measures, excluding in certain instances the impact of expenses related to other real estate owned, gains or losses on sale of investment securities, the charges associated with Pinnacle Financial's branch consolidation project, the sale of the remaining portion of Pinnacle Bank's non-prime automobile portfolio, expenses associated with Pinnacle Financial’s merger with BNC and other matters for the accounting periods presented. This presentation may also contain certain other non-GAAP capital ratios and performance measures that exclude the impact of goodwill and core deposit intangibles associated with Pinnacle Financial's acquisitions of BNC, Avenue Bank, Magna Bank, CapitalMark Bank & Trust, Mid-America Bancshares, Inc., Cavalry Bancorp, Inc. and other acquisitions which collectively are less material to the non-GAAP measure. The presentation of the non-GAAP financial information is not intended to be considered in isolation or as a substitute for any measure prepared in accordance with GAAP. Because non-GAAP financial measures presented in this presentation are not measurements determined in accordance with GAAP and are susceptible to varying calculations, these non-GAAP financial measures, as presented, may not be comparable to other similarly titled measures presented by other companies. Pinnacle Financial believes that these non-GAAP financial measures facilitate making period-to-period comparisons and are meaningful indications of its operating performance. In addition, because intangible assets such as goodwill and the core deposit intangible, and the other items excluded each vary extensively from company to company, Pinnacle Financial believes that the presentation of this information allows investors to more easily compare Pinnacle Financial's results to the results of other companies. Pinnacle Financial's management utilizes this non-GAAP financial information to compare Pinnacle Financial's operating performance for 2019 versus certain periods in 2018 and to internally prepared projections. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures is set forth in the appendix of this presentation.
