Report of Independent Registered Public Accounting Firm

Administrative Committee

Stifel Financial Profit Sharing 401(k) Plan

St. Louis, Missouri

We have audited the accompanying statements of net assets available for benefits of Stifel Financial Profit Sharing 401(k) Plan as of December 31, 2013 and 2012, 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 audit 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 auditing 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. Our audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management and 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 Stifel Financial Profit Sharing 401(k) Plan as of December 31, 2013 and 2012, and the changes in its 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 conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The accompanying supplementary information as listed in the table of contents is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental information is the responsibility of the Plan’s management. Such information has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

Stifel Financial Profit Sharing 401(k) Plan

Notes to Financial Statements

December 31, 2013 and 2012

NOTE 1 – Description of the Plan

The following description of the Stifel Financial Profit Sharing 401(k) Plan (the “Plan”) provides only general information. Participants should refer to the Plan document and Summary Plan Description for a more complete description of the Plan’s provisions.

General

The Plan, formerly known as the Stifel, Nicolaus Profit Sharing 401(k) Plan, is a defined contribution plan sponsored by Stifel Financial Corp. and affiliates (the “Company”) for the benefit of its employees who meet the eligibility provisions of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”). The Plan is administered by the Administrative Committee, whose members are appointed by the Company’s Board of Directors. Prudential Bank & Trust Company, FSB (“Prudential” or the “Trustee”) is a fiduciary of the Plan and also serves as the record keeper to maintain the individual accounts of each Plan participant.

Contributions

Each year, participants may contribute up to 100% of their eligible compensation as defined by the Plan document, up to an annual maximum of $17,500 for 2013. In addition, participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions through payroll deductions up to an annual maximum of $5,500 in 2013. For the years ended December 31, 2013 and 2012, the Company’s Board of Directors elected to match 50% of the first $2,000 contributed by each participant. The Company’s contribution to the participant’s individual account is credited at the end of the year. This is reflected in the employer contribution receivable in the statements of net assets available for benefits as of December 31, 2013 and 2012. The Company has the right, under the Plan, to discontinue or modify its matching contributions at any time.

In addition, each year the Company may make a discretionary contribution based on profitability. Discretionary contributions are allocated to the participants employed on the last day of the Plan year on the basis of participants’ compensation. There were no discretionary contributions in 2013 or 2012.

On December 12, 2012, the Company completed its acquisition of Miller Buckfire & Co. LLC (“Miller Buckfire”). On February 15, 2013, the Company completed its acquisition of KBW, Inc (“KBW”.) Effective December 31, 2013, the assets of the Miller Buckfire and KBW 401(k) Plans were merged into the Plan. The transfer included $15,134,910 and $147,418,152 of assets, respectively, which are included in Transferred from acquired company plan within the statement of changes in net assets available for benefits.

Effective October 1, 2013 the Parent merged the assets of the Stifel Financial Corp. Employee Stock Ownership Plan and Trust into the Plan. This merger included $32,372,789 of assets which are included in the Rollover from Stifel Financial Employee Stock Ownership Plan within the statement of changes in net assets available for benefits.

Participant Investment Account Options

Participants direct the investment of their contributions and the Company’s matching contributions into various investment account options offered by the Plan. The Plan currently offers investments in common stock of the Parent, various pooled separate accounts, mutual funds, a guaranteed account, and a self-directed brokerage accounts. Each participant has the option of directing their contributions into any of the separate investment accounts and may change the allocation daily.

Participant Accounts

Each participant’s account is credited with the participant’s and the Company’s contributions and allocations of plan earnings and is charged with an allocation of administrative expenses. Allocations are based on participant earnings or account balances, as defined. All amounts in participant accounts are participant directed.

4

Vesting

All elective contributions made by participants and earnings on those contributions are 100% vested at all times. Vesting in the Company’s contributions plus earnings thereon is based on years of service. A participant is fully vested after three years of service. Participants forfeit the nonvested portion of their accounts in the Plan upon termination of employment with the Company. Under provisions of the Plan, forfeited balances of terminated participants’ nonvested accounts may be used at the Company’s discretion to reduce its matching contribution obligations and then, to the extent any forfeitures remain, reallocated to participants’ accounts.

Payment of Benefits

Upon termination of service, an employee may elect to receive a lump-sum amount equal to the vested value of their account, net of any outstanding loan balance. Upon death, a participant’s account is paid in a lump sum to the designated beneficiary.

Notes Receivable from Participants

Participants may borrow from their fund accounts a minimum of $1,000 and up to a maximum of $50,000 or 50% of their vested account balance, whichever is less. Generally, loan terms may not exceed five years unless the loan is used to purchase a participant’s principal residence, in which case repayment terms may not exceed ten years. The loans are secured by the balance in the participant’s account and bear interest at a rate commensurate with local prevailing lending rates determined by the Administrative Committee. Principal and interest is paid ratably through payroll deductions.

Participant loans are classified as notes receivable from participants in the statements of net assets available for benefits and are measured at their unpaid principal balance plus any accrued but unpaid interest.

Plan Termination

Although it has not expressed an intention to do so, the Company has the right, under provisions of the Plan, to discontinue its contributions at any time and to terminate the Plan, subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts.

NOTE 2 – Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements are prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States may require management to make estimates and assumptions that affect the reported amounts of net assets available for plan benefits and changes therein. Actual results could differ from those estimates.

Valuation of Investments and Income Recognition

Pooled separate accounts are valued at estimated fair value as provided by the Trustee. The mutual funds, common stock and self-directed brokerage accounts are stated at fair value based upon quoted market prices. The Prudential Guaranteed Income Account is valued at contract value which equals fair value.

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

The Plan offers a fully-benefit responsive investment contract with Prudential as an investment option to Plan participants. Prudential maintains the contributions in a general account. The account is credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses. The contract is included in the financial statements at contract value as reported to the Plan by Prudential. Contract value represents contributions made by participants, plus interest at a specified rate determined semiannually. There is no market value adjustment upon discontinuance of a contract and no specific securities in the general account that back the liabilities of these contracts. The fair value for these contracts is equal to the contract value because there are no known cash flows that could be discounted.

5

There are no reserves against the contract value for credit risk of the contract issuer or otherwise. The stated rate of return of the contract was 2.15% and 2.50% for the years ended December 31, 2013 and 2012, respectively.

Income Tax Status

The Plan has not obtained or requested a determination letter from the Internal Revenue Service. However, the plan administrator believes that the Plan and related trust are currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code and that the Plan was qualified and the related trust was tax exempt as of the financial statement date.

Payment of Benefits

Benefit payments to participants are recorded upon distribution.

Risks and Uncertainties

The Plan provides for various investment options in common stock, registered investment companies (mutual funds), and short-term investments. The Plan’s exposure to credit loss in the event of nonperformance of investments is limited to the carrying value of such investments. Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility risk. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits and participant account balances.

NOTE 3 – Fair Value Measurements

Fair Value Hierarchy

The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with the Topic 820, “Fair Value Measurement and Disclosures,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the transparency of inputs as follows:

Level 1 – Observable inputs based on quoted prices in active markets for identical assets or liabilities;

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted market prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Valuation Techniques

The following is a description of the valuation techniques used to measure fair value on a recurring basis.

The Plan’s valuation methodology used to measure the fair values of the mutual funds, Stifel Financial Corp. common stock and self-directed brokerage accounts were derived from quoted market prices. These investments are reported as Level 1.

6

Pooled Separate Accounts

Fair value represents the net asset value (“NAV”) of the fund shares, which is calculated based on the valuation of the funds’ underlying investments at fair value at the end of the year. The investments are public investment vehicles, which are valued using the NAV provided by the Trustee, acting as the administrator of the fund. The NAV is based on the value of the underlying assets owned by the fund, excluding transaction costs, minus its liabilities, and then divided by the number of shares outstanding. The pooled separate accounts are reported as Level 2.

Guaranteed Income Fund

The Plan offers a fully-benefit responsive investment contract with Prudential as an investment option to Plan participants. Prudential maintains the contributions in a general account. The investment in the guaranteed income fund is reported at contract value. Contract value represents contributions made by participants, plus interest at a specified rate determined semiannually. There is no market value adjustment upon discontinuance of a contract and no specific securities in the general account that back the liabilities of these contracts. The fair value for these contracts is equal to the contract value because there are no known cash flows that could be discounted. The inputs used to estimate the fair value of the guaranteed income fund were derived from unobservable market data; therefore, the investment is reported as Level 3.

The following table summarizes the changes in fair value carrying values of the Plan’s Level 3 financial instruments during the years ended December 31, 2013 and 2012:

	Guaranteed Income Fund
Balance at December 31, 2011	$	56,347,272
Interest income		1,483,132
Purchases		12,477,592
Sales		(8,799,488	)
Balance at December 31, 2012		61,508,508
Interest income		1,533,915
Purchases		29,881,043
Sales		(9,232,310	)
Balance at December 31, 2013	$	83,691,156

The following table presents quantitative information related to the significant unobservable inputs utilized in the Plan’s recurring Level 3 fair value measurements as of December 31, 2013.

	Fair Value		Valuation technique		Unobservable input		Weighted average
Investment contract with insurance company	$	83,691,156		Discounted cash flow		Contractual Interest Rate		2.20	%

Changes in the contractual interest rate would result in a significant change in fair value to the extent the change deviates from changes in the market interest rates. Generally, an increase (decrease) in the difference between the contractual interest rate and the market interest rate is accompanied by a directionally opposed change in fair value.

NOTE 4 – Investments

The fair values of individual investments that represent 5% or more of the Plan’s net assets available for benefits at December 31, 2013 and 2012 were:

	December 31,
	2013			2012
Prudential Guaranteed Income Fund	$	83,691,156		$	61,508,508
Stifel Financial Corp. common stock		80,910,947			35,396,929
Fidelity Contrafund		*	*		23,988,780
TimesSquare Small Cap Growth		*	*		19,901,447

** Investment is less than 5% of net assets available for benefits.

For the years ended December 31, 2013 and 2012, the Plan’s investments including investments purchased and sold, as well as held during the year, appreciated/(depreciated) in fair value as follows:

	December 31,
	2013		2012
Stifel Financial Corp. common stock	$	21,485,663	$	(46,484	)

Pooled separate accounts		38,157,118		15,205,706
Self-directed brokerage accounts		4,023,902		1,332,670
	$	91,236,109	$	33,184,830

NOTE 5 – Party-in-Interest Transactions

Party-in-interest transactions include those with fiduciaries or employees of the Plan, any person who provides services to the Plan, an employer whose employees are covered by the Plan, and a person who owns 50% or more of such an employer or relatives of such persons.

As noted in Note 1 above, Prudential Bank & Trust Company, FSB is a fiduciary of the Plan and also serves as the record keeper to maintain the individual accounts of each participant.

Active participants can purchase the common stock of the Parent from their existing account balances. At December 31, 2013 and 2012, participants held 1,688,459 and 1,107,192 shares, respectively.

The Plan invests in certain funds of the Trustee. The Plan paid $43,690 and $36,805 of record keeping fees to the Trustee during 2013 and 2012, respectively. The Company provides certain administrative services at no cost to the Plan and pays certain accounting and auditing fees related to the Plan.

NOTE 6 – Subsequent Events

We evaluate subsequent events that have occurred after the net assets available for benefits date but before the financial statements are issued. Based on the evaluation, we did not identify any recognized subsequent events that would have required adjustment to the Plan’s financial statements.
