Report of Independent Registered Public Accounting Firm

To the Plan Administrator of

the Pinnacle Financial Partners, Inc. 401(k) Plan

We have audited the accompanying statements of net assets available for benefits of the Pinnacle Financial Partners, Inc. 401(k) Plan (the "Plan") as of December 31, 2012 and 2011, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2012 and 2011, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule H, line 4i – Schedule of Assets (Held at End of Year) is presented for the purpose of additional analysis and is not a required part of the 2012 basic financial statements but is supplementary information required by the Department of Labor Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements as of and for the year ended December 31, 2012, and, in our opinion, is fairly stated in all material respects in relation to the basic 2012 financial statements taken as a whole.

Notes to Financial Statements

December 31, 2012 and 2011

(1) Plan Description:

The following description of the Pinnacle Financial Partners, Inc. 401(k) Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions.

General: The Plan is a defined contribution plan covering all employees of Pinnacle Bank (the Sponsor) and its subsidiaries who are employed during such plan year and are age twenty-one or older. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions: Each year, participants may contribute up to 50% of pretax annual eligible compensation up to the maximum amount allowed by the Internal Revenue Service, as defined in the Plan. Effective January 1, 2010, participants may also make contributions on an after-tax basis (Roth 401k), subject to the same IRC limits when combined with their pretax contributions. Eligible compensation is defined as all income excluding fringe benefit income and income from stock appreciation rights, nonqualified stock options, incentive stock options, restricted stock awards and bonuses except for incentive bonuses, unless the associate elects otherwise. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. The Plan currently offers mutual funds and Pinnacle Financial Partners, Inc. common stock.

The Sponsor contributes 100% of the first 4% of eligible compensation that a participant contributes to the Plan. Additionally, the Sponsor may elect to make a discretionary contribution to the Plan. Participants who are not employed on the last working day of a Plan year are generally not eligible for the Sponsor's discretionary contribution to the Plan. As of December 31, 2012 and 2011, no discretionary contribution was made to the Plan by the Sponsor. The employer's contributions are invested according to the investment options chosen by the participant.

Participant Accounts: Each participant's account is credited with the participant's contribution and allocations of the Sponsor's contribution and Plan earnings. Allocations are based on participant account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account.

Vesting: Vesting in participants' and the Sponsor's contributions plus earnings thereon is immediate.

Notes Receivable from Participants: A participant may receive a loan based on the loan program set forth by the Plan. Active participants may borrow up to 50% of the vested portion of their accounts, subject to a $50,000 maximum. Loans are collateralized by participant accounts. Loans are repaid through payroll deductions over a maximum of five (5) years, unless the loan is for a primary residence, for which an extended term may be obtained. At December 2012, and 2011, notes receivable from participants totaled $860,651 and $768,898, respectively.

Notes to Financial Statements

December 31, 2012 and 2011

(1) Plan Description: (Continued)

Notes Receivable from Participants, (Continued): Current loans bear interest at rates between 3.25% and 7.25%. Notes receivable are stated at their unpaid principal balance plus accrued unpaid interest.

Cash Equivalents: The Plan considers cash and demand and time deposits with original maturities of three months or less as cash equivalents.

Operating Expenses: Operating and administrative expenses incurred by the Plan are absorbed by the Sponsor.

Payment of Benefits: On termination of service due to death, disability or retirement, a participant may elect to receive either a lump-sum amount equal to the value of the participant's vested interest in his or her account, annual installments, or an annuity. For termination of service due to other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution.

Other: Plan assets are held in trust by Capital Bank & Trust (the "Trustee").

(2) Summary of Significant Accounting Policies:

Basis of Accounting: The financial statements of the Plan are prepared using the accrual method of accounting.

Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Plan administrator to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results may differ from those estimates.

Investment Valuation and Income Recognition: The Plan's investments are stated at fair value. For investments, if available, quoted market prices are used to value investments. The amounts for securities that have no quoted market price represent estimated fair value. Many factors are considered in arriving at fair value. Shares of mutual funds are valued at quoted market prices which represent the net asset value of shares held by the Plan. As described in Accounting Standards Codification (ASC) 946-210, investment contracts held by a defined-contribution plan are required to be reported at fair value.

Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Interest income is recorded on the accrual basis.

Notes receivable from participants: Notes receivable from participants are recorded at their unpaid principal plus accrued and unpaid interest balance.

Payment of Benefits: Benefits are recorded when paid.

(3) Administration of Plan Assets:

The Plan's assets are held by the Trustee of the Plan. Contributions are held and managed by the Trustee, which invests cash received, interest and dividend income, and makes distributions to participants. Certain administrative functions are performed by officers or employees of the Sponsor. No such officer or employee receives compensation from the Plan.

Notes to Financial Statements

December 31, 2012 and 2011

(5) Related Party Transactions:

The Plan owned 1,433,104 and 1,487,329 shares of Pinnacle Financial Partners, Inc. common stock as of December 31, 2012 and 2011, respectively.

Also, certain Plan investments are shares of mutual funds managed by American Funds. The platform to administer the Plan is operated and maintained by American Funds and, therefore, the transactions qualify as party-in-interest transactions.

Fees are charged to the participant for loans and distributions. These fees totaled $3,002 and $2,182 for the years ended December 31, 2012 and 2011, respectively. These fees are considered customary and reasonable for such services.

(6) Fair Value of Financial Instruments:

ASC 820-10 defines fair value as the exchange price that would be received on the measurement date to sell an asset or the price paid to transfer a liability in the principal or most advantageous market available to the entity in an orderly transaction between market participants. ASC 820-10 also establishes a three level fair value hierarchy that describes the inputs that are used to measure assets and liabilities as follows:

Level 1

Level 1 asset and liability fair values are based on quoted prices in active markets for identical assets and liabilities. The Plan holds cash equivalents, mutual funds and common stock with total fair value at December 31, 2012 and 2011 of $55,121,683 and $45,487,485, respectively, which are measured as Level 1 assets.

Level 2

Level 2 asset and liability fair values are based on observable inputs that include: quoted market prices for similar assets or liabilities; quoted market prices that are not in an active market; or other inputs that are observable in the market and can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Plan has no Level 2 assets at December 31, 2012 and 2011.

Level 3

Level 3 assets and liabilities are financial instruments whose value is calculated by the use of pricing models and/or discounted cash flow methodologies, as well as financial instruments for which the determination of fair value requires significant management judgment or estimation. These methodologies may result in a significant portion of the fair value being derived from unobservable data. The Plan has no Level 3 assets at December 31, 2012 and 2011.

(7) Tax Status:

The "Basic Plan Document" was developed by the Plan's Trustee and submitted to the Internal Revenue Service (Service) for qualifications as a "prototype" plan. In its letter dated March 31, 2008, the Service opined that the form of this prototype plan is acceptable under Internal Revenue Code Section 401 for use by employers for the benefit of their employees. Although a determination letter has not been requested specifically for this Plan, the Plan's Trustees believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain tax position that more likely than not would not be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2012, there are no uncertain tax positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2009.

(8) Plan Termination:

The Sponsor reserves the right to terminate the Plan at any time, subject to the provisions of ERISA. Upon such termination of the Plan, the interest of each participant in the trust fund will be distributed to such participant or his or her beneficiary at the time prescribed by the Plan terms and the Internal Revenue Code. Upon termination of the Plan, the Trustee shall pay all liabilities and expenses of the trust.

(9) Risks and Uncertainties:

The Plan provides for various investment options in several investment securities and instruments. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks and values in the near term would materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits.

(10) Subsequent Events:

Management has evaluated subsequent events through June 26, 2013, the date the financial statements were available to be issued.

(11) Concentration:

At December 31, 2012 and 2011, approximately 49% and 53%, respectively, of Plan assets were invested in Pinnacle Financial Partners, Inc. common stock. A significant change in the stock price would have a significant effect on the financial statements.

(12) Net Assets:

Net assets available for benefits at December 31, 2012 and 2011, include $5,346,617 and $4,414,262, respectively, of vested benefits allocated to the accounts of participants who as of December 31, 2012 and 2011, had terminated employment with the Sponsor or a subsidiary affiliate thereof.
