The Company: We are a financial holding company that conducts its banking, securities and financial services business through several wholly owned subsidiaries. Our broker-dealer affiliates provide securities brokerage, investment banking, trading, investment advisory and related financial services to individual investors, professional money managers, businesses and municipalities.

The Offering: We are offering $200,000,000 principal amount of 4.25% Senior Notes due 2024 (the “new notes”). The new notes are being offered as additional notes under an indenture pursuant to which we previously issued $300,000,000 aggregate principal amount of 4.25% senior notes due 2024 (such previously issued notes, the “existing notes”). As used herein, the term “notes” refers to both the new notes and the existing notes. The new notes will be treated as a single series with the existing notes under the indenture governing the notes and will have the same terms and CUSIP number as the existing notes. The new notes and the existing notes will be fungible and will vote as one class under the indenture governing the notes. Immediately after giving effect to the issuance of the new notes offered hereby, we will have $500,000,000 aggregate principal amount of our 4.25% senior notes due 2024 outstanding.

Interest on the new notes will be deemed to have accrued from January 18, 2016 and will be paid semiannually in arrears on January 18 and July 18 of each year, commencing, with respect to the new notes, on July 18, 2016. The notes will mature on July 18, 2024. We may redeem the notes in whole or in part at our option at a redemption price equal to 100% of their principal amount, plus a “make-whole” premium and accrued and unpaid interest, if any, to the date of redemption, as described under “Description of Notes — Optional Redemption.” The notes will be issued in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof.

The notes will be our general unsecured senior obligations, will rank equally with all of our existing and future senior unsecured indebtedness and will be senior to any other indebtedness expressly made subordinate to the notes. The notes will be effectively subordinated to all of our existing and future secured indebtedness (to the extent of the value of the assets securing such indebtedness) and structurally subordinated to all existing and future liabilities of our subsidiaries, including trade payables.

We are concurrently offering depositary shares, each representing a 1/1000^th interest in a share of non-cumulative preferred stock, Series A, by means of a separate prospectus supplement (the “concurrent offering”). The offering of the new notes is not contingent upon the completion of the concurrent offering, and the concurrent offering is not contingent upon the completion of the offering of the new notes. There can be no assurance that the concurrent offering will be completed.

Investing in the new notes involves risks that are described in the “Risk Factors” section beginning on page S-5 of this prospectus supplement, and the documents incorporated by reference herein.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

THE OFFERING

The summary below describes the principal terms of the new notes. Some of the terms and conditions described below are subject to important limitations and exceptions. See “Description of Notes” for a more detailed description of the terms and conditions of the notes. All capitalized terms not defined herein have the meanings specified in “Description of Notes.”


Issuer		Stifel Financial Corp., a Delaware corporation.

Notes Offered		$200 million aggregate principal amount of 4.25% notes due 2024. The new notes are being offered as additional notes under the indenture pursuant to which we previously issued the existing notes. The new notes will be treated as a single series with the existing notes under the indenture and will have the same terms and CUSIP number as the existing notes. The new notes and the existing notes will be fungible and will vote as one class under the indenture governing the notes.

Offering Price		101.466% of the principal amount.

Maturity		The notes will mature on July 18, 2024, unless redeemed prior to maturity.

Interest Rate and Payment Dates		We will pay 4.25% interest per annum on the principal amount of the notes, payable semiannually in arrears on January 18 and July 18 of each year, commencing, with respect to the new notes, on July 18, 2016, and at maturity. Interest on the new notes will be deemed to have accrued from January 18, 2016.

Priority		The notes are our general unsecured senior obligations, ranking equally in right of payment with all of our existing and future senior indebtedness and will be senior to any other indebtedness expressly made subordinate to the notes. The notes are effectively junior to all of our existing and future secured obligations to the extent of the value of the assets securing such indebtedness. The notes are structurally subordinated to all existing and future indebtedness and liabilities of our subsidiaries.

Optional Redemption		We may redeem the notes, in whole or in part, at our option, at any time and from time to time, prior to maturity at a price equal to 100% of their principal amount, plus a “make-whole” premium and accrued and unpaid interest, if any, to the date of redemption. See “Description of Notes — Optional Redemption” for additional details.

Use of Proceeds		We will use the net proceeds from this offering to repay our outstanding 5.375% Senior Notes due 2022 and for other general corporate purposes,



		which may include the repayment of additional indebtedness. For additional information, see “Use of Proceeds.”

Further Issuances		We may create and issue further notes ranking equally and ratably with the notes in all respects, so that such further notes shall constitute and form a single series with the notes and shall have the same terms as to status, redemption or otherwise as the notes.

No Listing		We do not intend to list the notes on any securities exchange.

Form and Denomination		The new notes will be issued in fully registered form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Trustee and Paying Agent		U.S. Bank National Association.

Governing Law		The indenture and the notes will be governed by the laws of the State of New York.

Conflicts of Interest		Keefe, Bruyette & Woods, Inc. (“KBW”), our broker-dealer subsidiary, is a member of the Financial Industry Regulatory Authority (“FINRA”) and will participate in the distribution of the notes. Since we own more than 10% of the common equity of KBW, a “conflict of interest” exists for KBW within the meaning of FINRA Rule 5121(f)(5)(B). Additionally, KBW and one or more of its affiliates, as defined in FINRA Rule 5121, will have a conflict of interest as defined in Rule 5121(f)(5)(c)(ii) due to the receipt of more than 5% of the net offering proceeds. Accordingly, this offering will be conducted pursuant to Rule 5121. In accordance with that rule, no “qualified independent underwriter” is required because the securities offered are investment grade rated or are securities in the same series that have equal rights and obligations as investment grade rated securities. To comply with Rule 5121, the underwriters will not confirm sales of the securities to any account over which KBW exercises discretionary authority without the prior written approval of the customer. U.S. Bancorp Investments, Inc., an affiliate of the trustee, is one of the underwriters. See “Underwriting (Conflicts of Interest) — Conflicts of Interest.”

Concurrent Offering		We are concurrently offering depositary shares, each representing a 1/1000th interest in a share of non-cumulative preferred stock, Series A, by means of a separate prospectus supplement. The offering of the new notes is not contingent upon the completion of the concurrent offering, and the concurrent offering is not contingent upon the completion of the offering of the new notes. There can be no assurance that the concurrent offering will be completed.

Before you invest in the new notes, you should know that making such an investment involves significant risks, including the risks described below. You should carefully consider the following information about these risks, together with the other information contained in this prospectus and the information incorporated by reference, including risk factors contained in Part I, Item 1A of our Annual Report on Form 10-K, as amended by our Annual Report on Form 10-K/A, for the year ended December 31, 2015, before purchasing the new notes offered pursuant to this prospectus supplement. The risks that we have highlighted here are not the only ones that we face. For example, additional risks presently unknown to us or that we currently consider immaterial or unlikely to occur could also impair our operations. If any of the risks actually occurs, our business, financial condition or results of operations could be negatively affected.

As of March 31, 2016, after giving effect to this offering and the application of the proceeds thereof, our total long-term debt was approximately $882.5 million. As of March 31, 2016, we had approximately $269.4 million of consolidated secured, short-term indebtedness, all of which is held by Stifel Nicolaus, $500.0 million of borrowings from the Federal Home Loan Bank, which is held by Stifel Bank, and $58.2 million of term loans, which is held by Sterne Agee Group.

Our operations may not generate sufficient cash to enable us to service our debt. If we fail to make a payment on the notes, we could be in default on the notes, and this default could cause us to be in default on our other outstanding indebtedness. Conversely, a default on our other outstanding indebtedness may cause a default under the notes. In addition, we may incur additional indebtedness in the future, and, as a result, the related risks that we now face, including those described above, could intensify. The indenture for the notes will not restrict our ability to incur additional indebtedness.

The notes are our obligations and not obligations of our subsidiaries and will be structurally subordinated to the claims of our subsidiaries’ creditors.

The notes are exclusively our obligations and not those of our subsidiaries. We are a holding company and, accordingly, substantially all of our operations are conducted through our subsidiaries. As a result, our cash flow and our ability to service our debt, including the notes, depend upon the earnings of our subsidiaries. In addition, we depend on the distribution of earnings, loans or other payments by our subsidiaries to us. Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds to pay our obligations, whether by dividends, distributions, loans or other payments. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us would be subject to regulatory or contractual restrictions. Payments to us by our subsidiaries also will be contingent upon our subsidiaries’ earnings and business considerations.

Our right to receive any assets of any of our subsidiaries upon their liquidation or reorganization, and, therefore, the right of the holders of the notes to participate in those assets, will be structurally subordinated to the claims of those subsidiaries’ creditors, including senior and subordinated debtholders and general trade creditors. As of March 31, 2016, we had approximately $269.4 million of consolidated secured, short-term indebtedness, all of which is held by Stifel Nicolaus. In the event of any distribution of assets of Stifel Bank, the claims of depositors and other general or subordinated creditors would be entitled to priority over the claims of holders of the notes. In addition, even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of those subsidiaries and any indebtedness of those subsidiaries senior to that held by us.

We have made only limited covenants in the indenture governing the notes, and these limited covenants may not protect your investment.

Furthermore, the indenture for the notes contains only limited protections in the event of a change in control and does not require us to repurchase the notes upon a change of control. We could engage in many types of transactions, such as acquisitions, refinancings or recapitalizations, that could substantially affect our capital structure and the value of the notes. For these reasons, you should not consider the covenants in the indenture or the repurchase features of the notes as a significant factor in evaluating whether to invest in the notes.

We may redeem the notes before maturity, and you may be unable to reinvest the proceeds at the same or a higher rate of return.

We may redeem all or a portion of the notes at any time. The redemption price will equal the principal amount being redeemed, plus a “make-whole” premium and accrued and unpaid interest, if any, to the redemption date. See “Description of the Notes — Optional Redemption.” If a redemption does occur, you may be unable to reinvest the money you receive in the redemption at a rate that is equal to or higher than the rate of return on the notes.

In the absence of an active trading market for the notes, you may be unable to sell your notes or to sell your notes at a price that you deem sufficient.

The notes are not currently listed and we do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any automated dealer quotation system. Although we expect the new notes offered hereby will be fungible with the existing notes, for which a trading market currently exists, we cannot guarantee:

The liquidity of the trading market, if any, and future trading prices of the notes will depend on many factors, including, among other things, prevailing interest rates, our operating results, financial performance and prospects, the market for similar securities and the overall securities market, and may be adversely affected by unfavorable changes in these factors.

Current economic trends and pressure in the financial services industry could cause significant fluctuations in our results of operations and the trading price of the notes.

The results of operations of financial services firms, including us, have recently experienced significant price and volume fluctuations and downward pressure as a result of volatile market conditions and may continue to experience such pressures in the future. Our results of operations have been negatively impacted, and are likely to continue to be subject to fluctuations which may further negatively impact our operating performance or prospects, and may negatively impact the trading price of the notes. Factors that could significantly impact our results of operations and the trading price of the notes include:

Significant declines in results of operations or the trading price of the notes or failure of any of these items to increase could also harm our ability to recruit and retain key employees, including our executives and financial advisors and other key professional employees and those who have joined us from companies we have acquired, reduce our access to debt or equity capital, and otherwise harm our business or financial condition. In addition, we may not be able to use our debt securities to finance future acquisitions.

General market conditions and unpredictable factors could adversely affect the market value of the notes.

There can be no assurance about the market value of the notes. Several factors, many of which are beyond our control, will influence the market value of the notes. Factors that might influence the market value of the notes include:

Accordingly, the notes that an investor purchases, whether in the offering or in the secondary market, may trade at a discount to their cost, and their value will fluctuate.

The notes have been rated, but a rating agency may assign a rating to the notes that is lower than the ratings assigned to our other debt. A rating agency may also lower ratings on the notes in the future. If a rating agency assigns a lower-than-expected rating or reduces, or indicates that it may reduce, its ratings in the future, the trading price of the notes could significantly decline.

Our credit rating may not reflect all risks of an investment in the notes and there is no protection in the indenture for holders of the notes in the event of a ratings downgrade.

Our credit rating is an assessment by a rating agency of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit rating will generally affect the market value of the notes. The credit rating may not reflect the potential impact of risks relating to structure or marketing of the notes. A credit rating is not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. Neither we nor any underwriter undertakes any obligation to maintain the ratings or to advise holders of notes of any change in ratings. A credit rating by one agency should be evaluated independently of the credit ratings assigned by other agencies.

The summary historical financial information is derived from our audited consolidated financial statements as of December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014 and 2013, which are incorporated by reference into this prospectus supplement, and our audited financial statements as of December 31, 2013, 2012 and 2011 and for the years ended December 31, 2012 and 2011, which are not incorporated by reference into this prospectus supplement.

Our short-term financing is generally obtained through uncommitted, secured lines of credit and an unsecured revolving credit facility. We borrow from various banks on a demand basis with company-owned securities pledged as collateral to fund a portion of our daily operations. Additionally, we use customer securities pledged as collateral to fund customer borrowings. The amount borrowed under these credit facilities varies daily based on our funding needs.

Our uncommitted secured lines of credit at March 31, 2016 totaled $980.0 million with six banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. Our peak daily borrowing on our uncommitted secured lines was $356.7 million during the three months ended March 31, 2016. There are no compensating balance requirements under these arrangements. Any borrowings on secured lines of credit are generally utilized to finance certain fixed income securities. At March 31, 2016, our uncommitted secured lines of credit were collateralized by company-owned securities valued at $472.0 million.

Our committed short-term bank line financing at March 31, 2016 consisted of a $100.0 million committed revolving credit facility. The credit facility expires in December 2017. The applicable interest rate under the revolving credit facility is calculated as a per annum rate equal to LIBOR plus 2.00%, as defined in the revolving credit facility.

We can draw upon this line, as long as certain restrictive covenants are maintained. Under our revolving credit facility, we are also required to maintain compliance with a minimum consolidated tangible net worth covenant under which we are required to have at all times a consolidated tangible net worth, as defined in the revolving credit facility, and a maximum consolidated total capitalization ratio covenant under which we are required to have at all times a consolidated total capitalization ratio, as defined in the revolving credit facility. In addition, Stifel Nicolaus, our broker-dealer subsidiary, is required to maintain compliance with a minimum regulatory net capital covenant of not less than 10% of aggregate debits, as defined in the revolving credit facility.

At March 31, 2016, we had no advances on our revolving credit facility and were in compliance with all covenants. Our revolving credit facility contains customary events of default, including, without limitation, payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to similar obligations, certain events of bankruptcy and insolvency and judgment defaults.

Stifel Bank has borrowing capacity with the Federal Home Loan Bank of $2.0 billion at March 31, 2016 and a $25.0 million federal funds agreement, for the purpose of purchasing short-term funds should additional liquidity be needed. At March 31, 2016, outstanding FHLB advances were $500.0 million. Stifel Bank is eligible to participate in the Fed’s discount window program; however, Stifel Bank does not view borrowings from the Fed as a primary means of funding. The credit available in this program is subject to periodic review, may be terminated or reduced at the discretion of the Fed, and is secured by securities. Stifel Bank has borrowing capacity of $1.1 billion with the Fed’s discount window at March 31, 2016. Stifel Bank receives overnight funds from excess cash held in Stifel brokerage accounts, which are deposited into a money market account. These balances totaled $7.2 billion at March 31, 2016.

The Federal Home Loan advances as of March 31, 2016, are floating-rate advances. The weighted-average interest rates during the three months ended March 31, 2016, on these advances was 0.81%. The advances are secured by Stifel Bank’s residential mortgage loan portfolio and investment portfolio. The interest rates reset on a daily basis. Stifel Bank has the option to prepay these advances without penalty on the interest reset date.

As of March 31, 2016, a subsidiary of the Parent was a party to two Term Loans (“Term Loans”) with Regions Bank. The Term Loans mature on August 2, 2016. The interest rate under the Amended and Restated Credit Agreement is calculated as per annum rate equal to LIBOR, as defined. During the three months ended March 31, 2016, the weighted average interest rate on these term loans was 1.93%.

On December 18, 2012, we issued $150.0 million principal amount of 5.375% Senior Notes due 2022 (the “December 2012 Notes”). Interest on the December 2012 Notes accrued from December 21, 2012, and is paid quarterly in arrears on January 15, April 15, July 15, and October 15 of each year, commencing on April 15, 2013. The December 2012 Notes mature on December 31, 2022. We may redeem the December 2012 Notes in whole or in part on or after December 31, 2015, at our option, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest to the date of redemption. Proceeds from the December 2012 Notes issuance of $146.1 million, after discounts, commissions, and expenses, were used for general corporate purposes.

On December 1, 2015, we sold, in a registered underwritten public offering, $300.0 million in aggregate principal amount of 3.50% senior notes due December 2020 (the “2015 Notes”). Interest on the 2015 Notes is payable semi-annually in arrears. We may redeem the 2015 Notes in whole or in part, at our option, at a redemption price equal to 100% of their principal amount, plus a “make-whole” premium and accrued and unpaid interest, if any, to the date of redemption. Proceeds from the 2015 Notes issuance of $297.0 million, after discounts, commissions, and expenses, were used for general corporate purposes.

The 4.25% senior notes due 2024 offered hereby, which are referred to herein as the “new notes,” are an additional issuance of 4.25% senior notes due 2024. The new notes offered hereby will be treated as a single series with and will have the same terms and CUSIP number as the $300,000,000 aggregate principal amount of 4.25% senior notes due 2024, originally issued on July 18, 2014, which are referred to collectively herein as the “existing notes.” We will issue the new notes under the indenture dated as of January 23, 2012, between Stifel Financial Corp. and U.S. Bank National Association, as trustee (the “trustee”), as supplemented by the Third Supplemental Indenture dated as of July 18, 2014, with respect to the notes. We refer to the base indenture, as supplemented by the supplemental indenture, as the “indenture.” We will issue the new notes under the indenture, and the new notes and the existing notes will be fungible and will vote as one class under the indenture. As used herein, the term “notes” refers to both the new notes and the existing notes. The terms of the notes include those expressly set forth in the indenture and those made a part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The following summary of the terms of the notes and the indenture does not purport to be complete and is subject, and qualified in its entirety by reference, to the detailed provisions of the notes and the indenture, including the definitions of certain terms used in the indenture. You may request a copy of the indenture from us as described under “Where You Can Find More Information” in the accompanying prospectus. Those documents, and not this description, define your legal rights as a holder of the notes. The following description supplements, and supersedes to the extent it is inconsistent with, the statements under “Description of the Securities” in the accompanying prospectus.

For purposes of this description, the terms “Stifel Financial Corp.,” “we,” “us” and “our” refer only to Stifel Financial Corp. and not to any of its subsidiaries, unless we specify otherwise.

This offering of $200 million aggregate principal amount of new notes will constitute an additional issuance of the notes. The new notes offered hereby constitute “Additional Notes” under the indenture. The existing notes, the new notes offered hereby and any Additional Notes subsequently issued under the indenture will be fungible and will be treated as a single class for all purposes under the indenture, including, without limitation, waivers, amendments, redemptions, and offers to purchase. We may, without the consent of holders of the notes, increase the principal amount of the notes by issuing additional senior debt securities in the future on the same terms and conditions, except for any difference in the issue price and interest accrued prior to the issue date of the additional senior debt securities, and with the same CUSIP number as the notes offered hereby, provided that such additional senior debt securities constitute part of the same issue as the notes offered hereby for U.S. federal income tax purposes. The notes offered by this prospectus supplement and any additional senior debt securities would rank equally and ratably and would be treated as a single series of debt securities for all purposes under the indenture.

The notes will be issued only in fully registered, book-entry form, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, except under the limited circumstances described below under “ — Certificated Securities” in this prospectus supplement.

The indenture does not contain any provisions that would necessarily protect holders of notes if we become involved in a highly leveraged transaction, reorganization, merger or other similar transaction that adversely affects us or them.

We may, at our option, at any time and from time to time redeem the notes in whole or in part on not less than 30 nor more than 60 days’ prior notice mailed to the holders of the notes. The notes are redeemable at a redemption price equal to the greater of:

in each case, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. If the date of redemption is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the person in whose name the note is registered at the close of business on such interest record date, and no additional interest is payable to holders whose notes will be subject to redemption by us.

For purposes of this “— Optional Redemption” section, the following terms have the following meanings:

“Business Day” means any day that is not a Saturday, a Sunday or a day on which banking institutions are not required to be open in the City of New York.

“Comparable Treasury Issue(s)” means either (i) the United States Treasury security selected by an Independent Investment Banker as having an actual maturity, or (ii) two such securities selected by an Independent Investment Banker to be used to interpolate a maturity, in each case comparable to the remaining term of the notes to be redeemed that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes.

“Comparable Treasury Price” means, with respect to any date of redemption, the Reference Treasury Dealer Quotations for that date of redemption.

“Independent Investment Banker” means the Reference Treasury Dealer appointed by us.

“Reference Treasury Dealer” means each of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Keefe, Bruyette & Woods, Inc. and their respective successors and two other nationally recognized investment banking firms that are primary U.S. Government securities dealers specified from time to time by us so long as the entity is a primary U.S. Government securities dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any date of redemption, the average, as determined by us, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that date of redemption, after excluding the highest and lowest of such quotations, unless we obtain fewer than four such quotations, in which case the average of all of such quotations.

“Remaining Scheduled Payments” means, with respect to each note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related date of redemption therefor; provided, however, that, if that date of redemption is not an interest payment date with respect to such note, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to that date of redemption.

“Treasury Rate” means, with respect to any date of redemption, the rate per annum equal to the semiannual equivalent yield to maturity, computed as of the third Business Day immediately preceding that date of redemption, of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that date of redemption.

On and after any redemption date, interest will cease to accrue on the notes called for redemption. Prior to any redemption date, we are required to deposit with a paying agent money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on such date. If we are redeeming less than all the notes, the trustee under the indenture must select the notes to be redeemed on a pro rata basis or by such method as the trustee deems fair and appropriate in accordance with the procedures of the Depository Trust Company (“DTC”).

Except as described above, the notes will not be redeemable by us prior to maturity.

We may acquire notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the indenture or applicable law.

Interest on the notes will accrue at the rate of 4.25% per year, and will be payable semiannually in arrears on each January 18 and July 18. We will pay interest to those persons who were holders of record of such notes on the first day of the month of each interest payment date: January 1 and July 1, the record date preceding each interest payment date. Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. We will not provide a sinking fund for the notes. Interest on the new notes will be paid commencing on July 18, 2016, and will be deemed to have accrued from January 18, 2016. After July 18, 2016, interest will accrue from the date it was most recently paid.

If any interest payment date or stated maturity date is not a business day, the payment otherwise required to be made on such date will be made on the next business day without any additional payment as a result of such delay. The term “business day” means, with respect to any note, any day, other than a Saturday, Sunday or any other day on which banking institutions in The City of New York are authorized or obligated by law or executive order to close. All payments will be made in U.S. dollars.

The notes are our general unsecured senior obligations that rank senior in right of payment to our future indebtedness that is expressly subordinated in right of payment to the notes. The notes rank equally with all our other senior indebtedness. However, the notes are effectively junior to any of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. The notes will also be effectively junior to all liabilities, including trade payables and lease obligations of our subsidiaries. Any right by us to receive the assets of any of our subsidiaries upon a liquidation or reorganization of that subsidiary, and the consequent right of the holders of the notes to participate in those assets, will be structurally subordinated to the claims of that subsidiary’s creditors, except to the extent that we are recognized as a creditor of such subsidiary, in which case our claims would still be effectively junior to any security interests in the assets of such subsidiary and any indebtedness of such subsidiary that is senior to that held by us.

Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due on the notes or to make any funds available for payment on the notes, whether by dividends, loans or other payments. In addition, the payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to statutory, contractual or other restrictions, may depend on the earnings or financial condition of all of the foregoing and are subject to various business considerations. As a result, we may be unable to gain significant, if any, access to the cash flow or assets of our subsidiaries.

The indenture does not limit the amount of additional indebtedness, including senior or secured indebtedness, which we can create (other than the restrictions described in “Limitation on Liens” below), incur, assume or guarantee, nor does the indenture limit the amount of indebtedness or other liabilities that our subsidiaries can create, incur, assume or guarantee. As of March 31, 2016, after giving effect to this offering and the application of the proceeds thereof, our total long-term debt was $882.5 million, we had $269.4 million of consolidated secured, short-term indebtedness, which is held by Stifel Nicolaus, $500.0 million of borrowings from the Federal Home Loan Bank, which is held by Stifel Bank, and $58.2 million of term loans, which is held by Sterne Agee Group.

We, or any successor corporation, will not, and will not permit any subsidiary to, create, assume, incur or guarantee any indebtedness for borrowed money secured by a pledge, lien or other encumbrance, except for Permitted Liens, on the voting securities of any Principal Subsidiary unless we cause the notes (and if we so elect, any other of our indebtedness ranking on a parity with the notes) to be secured equally and ratably with (or, at our option, prior to) any indebtedness secured thereby.

“Permitted Liens” means (1) liens for taxes or assessment or governmental charges or levies (a) that are not then due and delinquent, (b) the validity of which is being contested in good faith or (c) which are less than $1,000,000 in amount; (2) judgment liens arising from any litigation or legal proceedings which (a) are currently being contested in good faith by appropriate proceedings or (b) which involve judgments of less than $5,000,000; (3) deposits to secure (or in lieu of) surety, stay, appeal or customs bonds; (4) liens imposed by law, such as carriers’, warehousemen’s and mechanics’ liens and other similar liens arising in the ordinary course of business which secure payment of obligations not more than 60 days past due or which are being contested in good faith by appropriate proceedings and for which adequate reserves shall have been set aside on its books; (5) liens arising out of pledges or deposits under worker’s compensation laws, unemployment insurance, old age pensions, or other social security or retirement benefits, or similar legislation; (6) any liens existing on the issue date; (7) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part, of any liens referred to in the foregoing clauses (3), (4), (5) and (6), provided that the principal amount of indebtedness secured thereby and not otherwise authorized as a Permitted Lien shall not exceed the principal of indebtedness, plus any premium or fee payable in connection with any such extension, renewal or replacement, so secured at the time of such extension, renewal or replacement; and (8) other liens arising in the ordinary course of business and consistent with past practice; and

“Principal Subsidiary” means any subsidiary of ours the total assets of which as set forth in the most recent statement of financial condition of such subsidiary equal more than 10% of the total consolidated assets of us and our subsidiaries as determined from the most recent consolidated statement of financial condition of us and our subsidiaries.

We will not, nor will we permit any of our Significant Subsidiaries to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property, other than any such Sale and Lease-Back Transaction involving a lease for a term of not more than three years or any such Sale and Lease-Back Transaction between us and one of our Significant Subsidiaries or between our Significant Subsidiaries, unless the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of the affected Principal Property (as

determined in good faith by the Board of Directors of the Company) and we apply an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back Transaction to any (or a combination) of (i) the prepayment or retirement of the notes, (ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at maturity) of other indebtedness of ours or of one of our Significant Subsidiaries (other than indebtedness that is subordinated to the notes or indebtedness owed to us or one of our Significant Subsidiaries) that matures more than 12 months after its creation or (iii) the purchase, construction, development, expansion or improvement of other comparable property.

“Attributable Debt” with regard to a Sale and Lease-Back Transaction with respect to any Principal Property means, at the time of determination, the present value of the total net amount of rent required to be paid under such lease during the remaining term thereof (including any period for which such lease has been extended), discounted at the rate of interest set forth or implicit in the terms of such lease (or, if not practicable to determine such rate, the weighted average interest rate per annum borne by the securities of all series then outstanding under the indenture) compounded semi-annually. In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount shall be the lesser of (x) the net amount determined assuming termination upon the first date such lease may be terminated (in which case the net amount shall also include the amount of the penalty, but shall not include any rent that would be required to be paid under such lease subsequent to the first date upon which it may be so terminated) or (y) the net amount determined assuming no such termination.

“Principal Property” means the land, improvements, buildings and fixtures (including any leasehold interest therein) constituting a corporate office, facility or other capital asset within the United States (including its territories and possessions) which is owned or leased by us or any of our Significant Subsidiaries unless our Board of Directors has determined in good faith that such office or facility is not of material importance to the total business conducted by us and our Significant Subsidiaries taken as a whole. With respect to any Sale and Lease-Back Transaction or series of related Sale and Lease-Back Transactions, the determination of whether any property is a Principal Property shall be determined by reference to all properties affected by such transaction or series of transactions.

“Sale and Lease-Back Transaction” means any arrangement with any person providing for the leasing by us or any of our Significant Subsidiaries of any Principal Property, whether now owned or hereafter acquired, which Principal Property has been or is to be sold or transferred by us or such Significant Subsidiary to such person; provided that Sale and Lease-Back Transaction shall not include any such arrangement in place as of the issue date.

“Significant Subsidiary” means, with respect to any person, any subsidiary of such person that satisfies the criteria for a “Significant Subsidiary” set forth in Rule 1-02(w) of Regulation S-X under the Exchange Act.

Notwithstanding the limitations on liens and Sale and Lease-Back Transactions described above, and without limiting our or any Significant Subsidiary’s ability to issue, incur, create, assume or guarantee indebtedness secured by Permitted Liens, we and any Significant Subsidiary will be permitted to incur indebtedness secured by a lien or may enter into a Sale and Lease-Back Transaction, in either case, without regard to the restrictions contained in the preceding two sections entitled “ — Limitations on Liens” and “ — Limitations on Sale and Lease-Back Transactions,” if at the time the indebtedness is incurred and after giving effect to such Indebtedness and to the retirement of indebtedness which is concurrently being retired, the sum of (a) the aggregate principal amount of all indebtedness secured by liens that are restricted by, and not otherwise permitted by, the provisions described under “ — Limitation on Liens” and (b) the Attributable Debt of all our Sale and Lease-Back Transactions not otherwise permitted by the provisions described under “ — Limitations on Sale and Lease-Back Transactions,” does not exceed 15% of Consolidated Net Worth (as defined below).

“Consolidated Net Worth” means, the consolidated stockholders’ equity of us and our subsidiaries, as defined according to GAAP.

The indenture generally permits us to consolidate or merge with another entity. The indenture also permits us to sell all or substantially all of our property and assets. If this happens, the remaining or acquiring entity must assume all of our responsibilities and liabilities under the indenture including the payment of all amounts due on the notes and performance of the covenants in the indenture. However, we will only consolidate or merge with or into any other entity or sell all or substantially all of our assets according to the terms and conditions of the indenture. The remaining or acquiring entity will be substituted for us in the indenture with the same effect as if it had been an original party to the indenture. Thereafter, the successor entity may exercise our rights and powers under any indenture, in our name or in its own name. Any act or proceeding required or permitted to be done by our board of directors or any of our officers may be done by the board or officers of the successor entity. When the successor assumes all of our obligations under the indenture, our obligations under the indenture will terminate.

If an event of default, other than an event of default referred to in the last bullet point above with respect to us (but including an event of default referred to in that bullet point solely with respect to a significant subsidiary, or group of subsidiaries that in the aggregate would constitute a significant subsidiary, of ours), has occurred and is continuing, either the trustee, by notice to us, or the holders of at least 25% in aggregate principal amount of the notes then outstanding, by notice to us and the trustee, may declare the principal of, and any accrued and unpaid interest on, all notes to be immediately due and payable. In the case of an event of default referred to in the last bullet point above with respect to us (and not solely with respect to a significant subsidiary, or group of subsidiaries that in the aggregate would constitute a significant subsidiary, of ours), the principal of, and accrued and unpaid interest on, all notes will automatically become immediately due and payable.

Notwithstanding the paragraph above, for the first 365 days immediately following an event of default relating to (i) our failure to file with the trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or (ii) our failure to comply with our reporting obligations to the trustee set forth under the second sub-bullet under the heading “ — Covenants” above, the sole remedy for any such event of default shall be the accrual of additional interest on the notes at a rate per year equal to (i) 0.25% of the outstanding principal amount of the notes for the first 180 days following the occurrence of such event of default and (ii) 0.50% of the outstanding principal amount of the notes for the next 180 days after the first 180 days following the occurrence of such event of default, in each case, payable quarterly at the same time and in the same manner as regular interest on the notes. This additional interest will accrue on all outstanding notes from, and including the date on which such event of default first occurs to, and including, the 365th day thereafter (or such earlier date on which such event of default shall have been cured or waived). In addition to the accrual of such additional interest, on and after the 360th day immediately following an event of default relating to such reporting obligations, either the trustee or the holders of not less than 25% in aggregate principal amount of the notes then outstanding may declare the principal amount of the notes and any accrued and unpaid interest through the date of such declaration, to be immediately due and payable.

If any portion of the amount payable on the notes upon acceleration is considered by a court to be unearned interest (through the allocation of a portion of the value of the notes to the embedded warrant or otherwise), the court could disallow recovery of any such portion.

After any acceleration of the notes, the holders of a majority in aggregate principal amount of the notes by written notice to the trustee, may rescind or annul such acceleration in certain circumstances, if::

Except as provided in the indenture, the holders of a majority of the aggregate principal amount of outstanding notes may, by notice to the trustee, waive any past default or event of default and its consequences, other than a default or event of default:

We will promptly notify the trustee upon our becoming aware of the occurrence of any default or event of default. In addition, the indenture requires us to furnish to the trustee, on an annual basis, an officer’s certificate stating whether they have actual knowledge of any default or event of default by us in performing any of our obligations under such indenture or the notes and describing any such default or event of default. If a default or event of default has occurred and the trustee has received notice of the default or event of default in accordance with the indenture, the trustee must mail to each registered holder of notes a notice of the default or event of default within 30 days after receipt of the notice. However, the trustee need not mail the notice if the default or event of default:

The indenture limits the right of holders of the notes to institute legal proceedings. No holder will have the right to bring a claim under the indenture unless:

Subject to the indenture, applicable law and the trustee’s rights to indemnification, the holders of a majority in aggregate principal amount of the outstanding notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee.

We may at any time elect to have all of our obligations discharged with respect to the outstanding notes (“legal defeasance”) except for the rights of holders of outstanding debt securities to receive payments in respect of the principal of, or interest or premium, if any, on, such debt securities when such payments are due from the trust referred to below, and except for certain of our other obligations and certain other rights of the trustee under the indenture.

In addition, we may at any time elect to have our obligations released with respect to certain covenants and thereafter any omission to comply with those covenants will not constitute a default or event of default with respect to the debt securities (“covenant defeasance”). In the event covenant defeasance occurs, certain events will no longer constitute an event of default with respect to the debt securities.

In order to exercise either legal defeasance or covenant defeasance, we must irrevocably deposit with the trustee for the benefit of the holders of the notes funds in amounts as will be sufficient to pay the principal of and premium, if any, and interest on the outstanding debt securities of such series on the stated date for payment thereof or on the applicable redemption date, as the case may be. In addition, we must deliver to the trustee certain opinions of counsel and officer’s certificate in connection with such defeasance, and we may not exercise such defeasance if certain defaults or events of default with respect to debt securities of such series have occurred and are continuing on the date of such deposit or if such defeasance would result in a breach or violation of, or constitute a default under, any material agreement or instrument to which we or any of our subsidiaries is a party or by which we or any of our subsidiaries are bound.

The indenture will be discharged and will cease to be of further effect with respect to the notes, when:

and we, in the case of the first, second and third sub-bullets above, have irrevocably deposited or caused to be deposited with the trustee as trust funds in trust solely for the benefit of the holders of debt securities of such series, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness (including all principal, premium, if any, and interest) on such notes delivered to the trustee for cancellation (in the case of notes that have become due and payable on or prior to the date of such deposit) or to the stated maturity or redemption date, as the case may be,

We may amend or supplement the indenture or the notes with the consent of the trustee and holders of at least a majority in aggregate principal amount of the outstanding notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes). In addition, subject to certain exceptions, the holders of a majority in aggregate principal amount of the outstanding notes may waive by consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes) our compliance with any provision of the indenture or notes. However, without the consent of the holders of each outstanding note affected, no amendment, supplement or waiver may:

We may, with the trustee’s consent, amend or supplement the indenture or the notes without notice to or the consent of any holder of the notes to:

We and the trustee may also enter into a supplemental indenture without the consent of holders of the notes in order to conform the indenture or the notes to the “Description of Notes” contained in this prospectus supplement.

The trustee for the notes is U.S. Bank National Association. We have appointed the trustee as the paying agent, and registrar with regard to the notes. The indenture permits the trustee to deal with us and any of our affiliates with the same rights the trustee would have if it were not trustee. However, under the Trust Indenture Act, if the trustee acquires any conflicting interest and there exists a default with respect to the notes, the trustee must eliminate the conflict or resign. The trustee and its affiliates have in the past provided or may from time to time in the future provide banking and other services to us in the ordinary course of their business. U.S. Bancorp Investments, Inc., an affiliate of the Trustee, is one of the underwriters.

The holders of a majority in aggregate principal amount of the notes then outstanding have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, subject to certain exceptions. If an event of default occurs and is continuing, the trustee must exercise its rights and powers under the indenture using the same degree of care and skill as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. The indenture does not obligate the trustee to exercise any of its rights or powers at the request or demand of the holders, unless the holders have offered to the trustee security or indemnity that is reasonably satisfactory to the trustee against the costs, expenses and liabilities that the trustee may incur to comply with the request or demand.

The notes will be issued in registered form, without interest coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, in the form of global securities. We will not impose a service charge in connection with any transfer or exchange of any note. See “ — Global Notes; Book-Entry Form” for a description of transfer restrictions that apply to the notes.

Global notes will be deposited with the trustee as custodian for The Depository Trust Company (“DTC”) and registered in the name of DTC or a nominee of DTC.

Beneficial interests in a global note may be held directly through DTC if the holder is a participant in DTC or indirectly through organizations that are participants in DTC.

Except in the limited circumstances described below and in “ — Certificated Securities,” holders of notes will not be entitled to receive notes in certificated form. Unless and until it is exchanged in whole or in part for certificated securities, each global note may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC.

We will apply to DTC for acceptance of the global securities in its book-entry settlement system. The custodian and DTC will electronically record the principal amount of notes represented by global securities held within DTC. Beneficial interests in the global securities will be shown on records maintained by DTC and its direct and indirect participants, including Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking, société anonyme (“Clearstream”). Investors may elect to hold interests in the global notes through either DTC in the U.S. or Clearstream or Euroclear in Europe if they are participants of such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC.

So long as DTC or its nominee is the registered owner or holder of a global note, DTC or such nominee will be considered the sole owner or holder of the notes represented by such global note for all purposes under the indenture and the notes. No owner of a beneficial interest in a global note will be able to transfer such interest except in accordance with DTC’s applicable procedures and the applicable procedures of its direct and indirect participants. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. These limitations and requirements may impair the ability to transfer or pledge beneficial interests in a global note.

Payments of principal, premium, if any, and interest under each global note will be made to DTC or its nominee as the registered owner of such global note. We expect that DTC or its nominee, upon receipt of any such payment, will immediately credit DTC participants’ accounts with payments proportional to their respective beneficial interests in the principal amount of the relevant global note as shown on the records of DTC. We also expect that payments by DTC participants to owners of beneficial interests will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of

customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants, and none of us, the trustee, the custodian or any paying agent or registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in any global note or for maintaining or reviewing any records relating to such beneficial interests.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Exchange Act. DTC was created to hold the securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, which eliminates the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own the depository. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The ownership interest and transfer of ownership interests of each beneficial owner or purchaser of each security held by or on behalf of DTC are recorded on the records of the direct and indirect participants.

Clearstream advises that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

Distributions with respect to interests in the notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

Euroclear advises that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of Euroclear, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without

attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no records of or relationship with persons holding through Euroclear Participants.

Distributions with respect to the notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions.

The information in this section concerning DTC, DTC’s book-entry system, Clearstream and Euroclear has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

Neither we nor the trustee will be liable or responsible for DTC, Euroclear or Clearstream.

The trustee will exchange beneficial interests in a global note for one or more certificated securities registered in the name of the owner of the beneficial interest, as identified by DTC, only if:

We will make payments in respect of notes represented by global securities by wire transfer of immediately available funds to DTC or its nominee as registered owner of the global securities.

We expect the notes will trade in DTC’s Same-Day Funds Settlement System, and DTC will require all permitted secondary market trading activity in the notes to be settled in immediately available funds. We expect that secondary trading in any certificated securities will also be settled in immediately available funds.

Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds.

Although DTC has agreed to the above procedures to facilitate transfers of interests in the global securities among DTC participants, DTC is under no obligation to perform or to continue those procedures, and those procedures may be discontinued at any time. None of us, the underwriters or the trustee will have any responsibility for the performance by DTC or its direct or indirect participants of their respective obligations under the rules and procedures governing their operations.

The indenture and the notes will be governed by and construed in accordance with the laws of the State of New York.

The following is a summary of the material United States federal income tax consequences of the purchase, ownership, and disposition of the new notes. This summary is generally limited to holders that acquire the new notes pursuant to this offering at their offering price and hold the new notes as “capital assets” (generally, property held for investment) for United States federal income tax purposes. This discussion does not describe all of the United States federal income tax consequences that may be relevant to a holder in light of its particular circumstances or to holders subject to special rules, including, without limitation, tax-exempt organizations, holders subject to the United States federal alternative minimum tax, dealers in securities or currencies, financial institutions, insurance companies, regulated investment companies, real estate investment trusts, certain former citizens or residents of the United States, controlled foreign corporations, passive foreign investment companies, partnerships, S corporations or other pass-through entities, U.S. holders (as defined below) whose functional currency is not the United States dollar, and persons that hold the new notes in connection with a straddle, hedging, conversion or other risk-reduction transaction.

The United States federal income tax consequences set forth below are based upon the Internal Revenue Code of 1986, as amended (the “Code”) and applicable Treasury regulations promulgated thereunder, court decisions, and rulings and pronouncements of the Internal Revenue Service (“IRS”), all as in effect on the date hereof, and all of which are subject to change, or differing interpretations at any time with possible retroactive effect. There can be no assurance that the IRS will not challenge one or more of the tax consequences described herein, and we have not sought any ruling from the IRS with respect to statements made and conclusions reached in this discussion, and there can be no assurance that the IRS will agree with such statements and conclusions.

As used herein, the term “U.S. holder” means a beneficial owner of a new note that is for U.S. federal income tax purposes:

As used herein, the term “non-U.S. holder” means a beneficial owner of a new note that is neither a U.S. holder nor a partnership or an entity treated as a partnership for U.S. federal income tax purposes.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a new note, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. A beneficial owner that is a partnership and partners in such a partnership should consult their tax advisors about the U.S. federal income tax consequences of the purchase, ownership and disposition of the new notes.

This summary does not address the tax consequences arising under any state, local, or foreign law. Furthermore, this summary does not consider the effect of the U.S. federal estate or gift tax laws.

Investors considering the purchase of the new notes should consult their tax advisors with respect to the application of the U.S. federal income tax laws to their particular situation, as well as any tax consequences arising under the U.S. federal estate or gift tax rules or under the laws of any state, local, or foreign taxing jurisdiction or under any applicable tax treaty.

The new notes will be issued with no more than a de minimis amount of original issue discount, and therefore will be issued pursuant to a “qualified reopening” of the existing notes. For U.S. federal income tax purposes, debt instruments issued in a qualified reopening are deemed to be part of the same issue as the original debt instruments. Under the treatment described in this paragraph, all of the new notes issued pursuant to this prospectus supplement will be deemed to have the same issue date and the same issue price as the existing notes for U.S. federal income tax purposes.

A portion of the price paid for the new notes offered hereby is attributable to interest that accrued prior to the date the new notes offered hereby are purchased (the “pre-issuance accrued interest”). Because the issue price of the new notes as determined for U.S. federal income tax purposes excludes any pre-issuance accrued interest, a portion of the stated interest payment on July 18, 2016 on the new notes equal to any pre-issuance accrued interest will be treated as a return of such pre-issuance accrued interest and will not be taxable as interest on the new notes.

Payments of stated interest on a new note will be included in the gross income of a U.S. holder as ordinary interest income at the time such payments are accrued or are received (in accordance with the U.S. holder’s regular method of tax accounting).

Generally, a U.S. holder who purchases a note at a cost that exceeds the note’s stated principal amount will be considered to have purchased the note with “bond premium” in an amount equal to such excess. A U.S. holder may elect to amortize the premium as an offset to interest income, using a constant yield method, over the remaining term of the note, subject to certain limitations when the note is subject to early redemption at a premium. If a U.S. holder makes an election to amortize the premium, such election generally will apply to all debt instruments that such U.S. holder holds at the time of the election, as well as any debt instruments that such U.S. holder subsequently acquires. In addition, a U.S. holder may not revoke the election without the consent of the IRS. If a U.S. holder elects to amortize the premium, such U.S. holder will be required to reduce its tax basis in the new note by the amount of the premium amortized during its holding period. If a U.S. holder does not elect to amortize premium, the amount of premium will be included in such U.S. holder’s tax basis in the new note purchased in this offering and, therefore, such premium will decrease the gain or increase the loss that such U.S. holder would otherwise recognize on disposition of the new note.

A U.S. holder will generally recognize gain or loss on the sale, redemption, exchange, or other taxable disposition of a new note, in an amount equal to the difference between (i) the amount realized by the holder in the disposition and (ii) the U.S. holder’s adjusted tax basis in the new note. The amount realized by a U.S. holder will include the amount of any cash and the fair market value of any other property received for the new note (less any portion allocable to any accrued and unpaid interest, which will be taxed as ordinary interest income to the extent not previously so taxed). In general, a U.S. holder’s adjusted tax basis in a new note will equal the amount paid for the new note (excluding the amount paid for pre-issuance accrued interest), decreased by any amortized bond premium. Such gain or loss recognized by a U.S. holder on a disposition of a new note generally will be capital gain or loss and generally will be long-term capital gain or loss if the holder held the

new note for more than one year. Under current U.S. federal income tax law, net long-term capital gains of non-corporate U.S. holders (including individuals) are eligible for taxation at preferential rates. The deductibility of capital losses is subject to certain limitations. Prospective investors should consult their tax advisors concerning these tax law provisions.

Certain U.S. holders who are individuals, estates or trusts are subject to an additional 3.8% tax on all or a portion of their “net investment income”, which includes, among other things, interest on the new notes and capital gain from the sale or other taxable disposition of the new notes. U.S. holders should consult their tax advisors regarding the effect, if any, of the Medicare tax on their ownership and disposition of the new notes.

Unless a U.S. holder is an exempt recipient, such as a corporation, payments made with respect to the new notes may be subject to information reporting and may also be subject to U.S. federal backup withholding at the applicable rate if a U.S. holder fails to comply with applicable United States information reporting and certification requirements.

Backup withholding is not an additional tax. Any amount withheld from you under the backup withholding rules generally will be allowed as a refund or a credit against your United States federal income tax liability, provided the required information is furnished timely to the IRS.

Subject to the discussions below concerning backup withholding and FATCA (as defined below), interest paid on a new note by us or our agent to a non-U.S. holder will qualify for the “portfolio interest exemption” and will not be subject to U.S. federal income tax or withholding tax; provided that such interest income is not effectively connected with a U.S. trade or business of the non-U.S. holder (and, if a tax treaty applies, is not attributable to a U.S. permanent establishment or fixed base maintained by the non-U.S. holder within the United States); and provided that the non-U.S. holder:

If such non-U.S. holder cannot satisfy the requirements described above, payments of interest made to the non-U.S. holder will be subject to the 30% United States federal tax withholding unless such holder provides us

with (1) a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or a suitable substitute form), claiming an exemption from (or reduction of) withholding under the benefit of a treaty, or (2) a properly completed and executed IRS Form W-8ECI (or a suitable substitute form) certifying that interest paid on the note is not subject to withholding tax.

Income Effectively Connected with a Trade or Business within the United States

If interest on a new note is effectively connected with a United States trade or business by a non-U.S. holder and, if a tax treaty applies, is attributable to a United States permanent establishment or fixed base maintained by the non-U.S. holder within the United States, the non-U.S. holder generally will not be subject to withholding if the non-U.S. holder complies with applicable IRS certification requirements (i.e., by delivering a properly executed IRS Form W-8ECI) and generally will be subject to United States federal income tax on a net-income basis at regular graduated rates in the same manner as if the holder were a U.S. holder. In the case of a non-U.S. holder that is a corporation, such effectively connected income also may be subject to the additional branch profits tax, which generally is imposed on a foreign corporation on the deemed repatriation from the United States of effectively connected earnings and profits at a 30% rate (or such lower rate as may be prescribed by an applicable tax treaty).

Subject to the discussions below on back up withholding and FATCA, generally, any gain recognized by a non-U.S. holder on the disposition of a new note will not be subject to United States federal income tax and withholding, unless:

If you are a non-U.S. holder described in the first bullet point above, you generally will be subject to tax as described above (See “ — Non-U.S. Holders — Income Effectively Connected with a Trade or Business within the United States”). If you are a non-U.S. holder described in the second bullet point above, you generally will be subject to a flat 30% (or lower applicable treaty rate) U.S. federal income tax on the gain derived from the sale, redemption, exchange, retirement or other disposition, which may be offset by certain U.S. source capital losses. A non-U.S. holder should consult his or her tax advisor regarding the tax consequences of the purchase, ownership and disposition of the new notes.

Non-U.S. holders may be required to comply with certain certification procedures to establish that the holder is not a United States person in order to avoid information reporting and backup withholding.

Non-U.S. holders should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedures for obtaining such an exemption, if available.

Sections 1471-1474 of the Code (known as FATCA) impose certain due diligence and information reporting requirements, particularly with respect to accounts held through foreign financial institutions. A 30% U.S. federal withholding tax will apply to interest income from debt obligations of U.S. issuers, and, effective for payments made after December 31, 2018, a 30% U.S. withholding tax will apply on the gross proceeds from a disposition of such obligations, in each case, paid to a foreign financial institution (including in certain instances where such institution is acting as an intermediary), unless such institution enters into an agreement with the U.S. Treasury Department to collect and provide to the Treasury Department substantial information regarding U.S. account holders, including certain account holders that are foreign entities with U.S. owners, with such institution. The 30% U.S. federal withholding tax will also apply to interest income from such obligations and on the gross proceeds from the disposition of such obligations paid to a non-financial foreign entity (including in certain instances where such entity is acting as an intermediary) unless such entity provides the withholding agent with a certification that it does not have any substantial U.S. owners or a certification identifying the direct and indirect substantial U.S. owners of the entity. Under certain circumstances, a holder may be eligible for refunds or credits of such taxes. The United States has entered into (and may enter into more) intergovernmental agreements (“IGAs”) with foreign governments relating to the implementation of, and information sharing under, FATCA and such IGAs may alter the FATCA reporting and withholding requirements.

Application of this withholding tax does not depend on whether the payment otherwise would be exempt from U.S. federal withholding tax under an exemption described under “ — Non-U.S. Holders.” In the event that this withholding tax shall be imposed on any payment of interest on, or gross proceeds from the disposition or redemption of, a note, we have no obligation to pay additional amounts as a consequence thereof or to redeem the new notes before their stated maturity. Investors are urged to consult with their own tax advisors regarding the possible implications of FATCA on their investment in the new notes.

The United States federal income tax summary set forth above is included for general information only and may not be applicable depending upon your particular situation. You should consult your tax advisors with respect to the tax consequences to you of the purchase of the new notes, and the ownership and disposition of the new notes, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in federal or other tax laws.

Keefe, Bruyette & Woods, Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. LLC are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in a firm commitment underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of new notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the new notes sold under the underwriting agreement if any of the new notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the new notes, subject to prior sale, when, as and if issued to and accepted by them, subject to conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The representatives have advised us that the underwriters propose initially to offer the new notes to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of 0.65% of the principal amount of the new notes. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The expenses of the offering, not including the underwriting discount, are estimated at $350,000 and are payable by us.

In addition, we have agreed to pay for the FINRA-related fees and expenses of the underwriters’ legal counsel, not to exceed $30,000.

We have agreed that we will not, for a period from the date of this offering memorandum through and including the business day following the date of delivery of the notes, without first obtaining the prior written

consent of the representatives, directly or indirectly, issue, sell, offer to contract or grant any option to sell, pledge, transfer or otherwise dispose of, any debt securities or securities exchangeable for or convertible into debt securities, except for the new notes sold to the underwriters pursuant to the underwriting agreement.

In connection with the offering, the underwriters may purchase and sell the new notes in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater principal amount of new notes than they are required to purchase in the offering. The underwriters must close out any short position by purchasing new notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the new notes in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the new notes or preventing or retarding a decline in the market price of the new notes. As a result, the price of the new notes may be higher than the price that might otherwise exist in the open market.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the new notes. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

In connection with the offering, certain of the underwriters or securities dealers may distribute this prospectus supplement and the accompanying prospectus by electronic means, such as e-mail.

Keefe, Bruyette & Woods, Inc. (“KBW”), our broker-dealer subsidiary, is a member of the FINRA and will participate in the distribution of the new notes. Since we own more than 10% of the common equity of KBW, a “conflict of interest” exists for KBW within the meaning of FINRA Rule 5121(f)(5)(B). Additionally, KBW and one or more of its affiliates, as defined in FINRA Rule 5121, will have a conflict of interest as defined in Rule 5121(f)(5)(c)(ii) due to the receipt of more than 5% of the net offering proceeds. Accordingly, this offering will be conducted pursuant to Rule 5121. In accordance with that rule, no “qualified independent underwriter” is required because the securities offered are investment grade rated or are securities in the same series that have equal rights and obligations as investment grade rated securities. To comply with Rule 5121, the underwriters will not confirm sales of the securities to any account over which KBW exercises discretionary authority without the prior written approval of the customer.

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. An affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated is a co-lender under a $100 million unsecured revolving credit facility and secured, short-term lines of credit available to us. U.S. Bancorp Investments, Inc., an affiliate of the trustee, is one of the underwriters. US Bancorp Investments, Inc. and certain of its affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management practices.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the new notes offered hereby. Any such short positions could adversely affect future trading prices of the new notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Certain of the underwriters or their affiliates are also acting as underwriters in connection with the concurrent offering.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”), no offer of new notes may be made to the public in that Relevant Member State other than:

provided that no such offer of new notes shall require the Company or the representatives to publish a prospectus pursuant to Article 3 of the Prospectus Directive or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

This prospectus has been prepared on the basis that any offer of new notes in any Relevant Member State will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of new notes. Accordingly, any person making or intending to make an offer in that Relevant Member State of new notes which are the subject of the offering contemplated in this prospectus may only do so in circumstances in which no obligation arises for the Company or any of the underwriters to publish a prospectus pursuant to Article 3 of the Prospectus Directive in relation to such offer. Neither the Company nor the underwriters have authorized, nor do they authorize, the making of any offer of new notes in circumstances in which an obligation arises for the Company or the underwriters to publish a prospectus for such offer.

For the purpose of the above provisions, the expression “an offer to the public” in relation to any new notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the new notes to be offered so as to enable an investor to decide to purchase or subscribe for the new notes, as the same may be varied in the Relevant Member State by any measure implementing the Prospectus Directive in the Relevant Member State and the expression “Prospectus Directive” means Directive 2003/71/EC (including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member States) and includes any relevant implementing measure in the Relevant Member State and the expression “2010 PD Amending Directive” means Directive 2010/73/EU.

In addition, in the United Kingdom, this document is being distributed only to, and is directed only at, and any offer subsequently made may only be directed at persons who are “qualified investors” (as defined in the Prospectus Directive) (i) who have professional experience in matters relating to investments falling within Article 19 (5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Order”) and/or (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (d) of the Order (all such persons together being referred to as “relevant persons”). This document must not be acted on or relied on in the United Kingdom by persons who are not relevant persons. In the United Kingdom, any investment or investment activity to which this document relates is only available to, and will be engaged in with, relevant persons.

We are a financial holding company headquartered in St. Louis. Our principal subsidiary is Stifel, Nicolaus & Company, Incorporated, a full-service retail and institutional brokerage and investment banking firm. Our other subsidiaries include Century Securities Associates, Inc., an independent contractor broker-dealer firm; Keefe, Bruyette & Woods, Inc., and Miller Buckfire & Co., LLC, broker-dealer firms; Stifel Nicolaus Europe Limited, Keefe, Bruyette & Woods Limited, and Oriel Securities Limited, our European broker-dealer subsidiaries; Stifel Bank & Trust, a retail and commercial bank; and Stifel Trust Company, N.A.

With our century-old operating history, we have built a diversified business serving private clients, investment banking clients and institutional investors. Our principal activities are:

Our core philosophy is based upon a tradition of trust, understanding, and studied advice. We attract and retain experienced professionals by fostering a culture of entrepreneurial, long-term thinking. We provide our private, institutional and corporate clients quality, personalized service, with the theory that if we place clients’ needs first, both our clients and our company will prosper. Our unwavering client and employee focus have earned us a reputation as one of the leading brokerage and investment banking firms off Wall Street.

We have grown our business both organically and through opportunistic acquisitions, including our acquisition of the capital markets business of Legg Mason from Citigroup in 2005; our acquisitions of Ryan Beck & Co., Inc. in February 2007 and FirstService Bank in April 2007; our acquisition of ButlerWick & Co., Inc. in 2008; our acquisition of 56 branches from the UBS Wealth Management Americas branch network in 2009; our acquisition of Thomas Weisel Partners Group, Inc. in July 2010; our acquisition of Stone & Youngberg in October 2011; our merger with KBW in February 2013; our acquisition of the U.S. institutional fixed income sales and trading business and the hiring of the European institutional fixed income sales and trading team from Knight Capital Group in July 2013; our acquisition of Acacia Federal Savings Bank in October 2013; our acquisition of Ziegler Lotsoff Capital Management, LLC in November 2013; our acquisition of De La Rosa & Co. in April 2014; our acquisition of Oriel Securities in July 2014; our acquisition of Legg Mason Investment Counsel & Trust Co., N.A. in November 2014; and our acquisition of Merchant Capital, LLC in December 2014. Throughout the course of these integrations, our highly variable cost structure has enabled us to achieve consistent core earnings profitability while growing net revenue for 18 consecutive years.

We primarily operate our business through two segments, Global Wealth Management and Institutional Group. Our Global Wealth Management segment consists of two businesses, the Private Client Group and Stifel Bank. The Private Client Group provides securities brokerage services, including the sale of equities, mutual funds, fixed income products, and insurance, as well as offering banking products to our clients through Stifel Bank. Stifel Bank provides residential, consumer, and commercial lending, as well as FDIC-insured deposit accounts to customers of our broker-dealer subsidiaries and to the general public.

Our Institutional Group segment includes institutional sales and trading. It provides securities brokerage, trading, and research services to institutions, with an emphasis on the sale of equity and fixed income products. This segment also includes the management of and participation in underwritings for both corporate and public finance (exclusive of sales credits generated through the private client group, which are included in the Global Wealth Management segment), merger and acquisition, and financial advisory services.

For the year ended December 31, 2013, Global Wealth Management net revenues increased 12.7% to a record $1.12 billion from $991.6 million in 2012. For the nine months ended September 30, 2014, Global Wealth Management net revenues increased 11.8% to a record $921.7 million from $824.3 million for the comparable period in 2013. For the year ended December 31, 2013, Institutional Group net revenues increased 42.4% to a record $861.2 million from $604.7 million in 2012. For the nine months ended September 30, 2014, Institutional Group net revenues increased 21.4% to $720.8 million from $593.9 million for the comparable period in 2013.

We believe that our Global Wealth Management segment provides balance with respect to our Institutional Group segment and creates a stable base of revenue that helps us achieve consistent profitability through market cycles.

Our customers include individuals, corporations, municipalities, and institutions. We have customers throughout the United States with geographic areas of concentration in the Northeast, Midwest, Mid-Atlantic, and Western regions, with a growing presence in the Southeastern United States. No single client accounts for a material percentage of any segment of our business. Our inventory, which we believe is of modest size and intended to turn over quickly, exists to facilitate order flow and support the investment strategies of our clients. Although we do not engage in significant proprietary trading for our own account, the inventory of securities held to facilitate customer trades and our market-making activities are sensitive to market movements. Furthermore, our balance sheet is highly liquid, without material holdings of securities that are difficult to value or remarket. We believe that our broad platform, fee-based revenues, and strong distribution network position us well to take advantage of current trends within the financial services sector.

An investment in our securities involves risks. We urge you to consider carefully the risks described in the documents incorporated by reference in this prospectus and, if applicable, in any prospectus supplement used in connection with an offering of our securities, before making an investment decision, including those risks identified under “Risk Factors” in Item 1A of Part I in our Annual Report on Form 10-K for the year ended December 31, 2013, which is incorporated by reference in this prospectus and which may be amended, supplemented or superseded from time to time by other reports that we subsequently file with the SEC. Additional risks, including those that relate to any particular securities we offer, may be included in a prospectus supplement or free writing prospectus that we authorize from time to time, or that are incorporated by reference into this prospectus or a prospectus supplement.

Our business, financial condition, results of operations and cash flows could be materially adversely affected by any of these risks. The market or trading price of our securities could decline due to any of these risks. Additional risks not presently known to us or that we currently deem immaterial also may impair our business and operations or cause the price of our securities to decline.

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds of any offering of securities sold by us for general corporate purposes. Unless otherwise set forth in a prospectus supplement, we will not receive any proceeds in the event that the securities are sold by a selling security holder.

⁽¹⁾ For the year ended December 31, 2010, we recorded a non-cash charge of $106.4 million after-tax related to the acceleration of deferred compensation in the third quarter of 2010 as a result of a modification of our deferred compensation plan and merger-related after-tax expenses of $16.5 million related to the merger with Thomas Weisel Partners Group, Inc. Our earnings were insufficient to cover fixed charges by $1.5 million for the year ended December 31, 2010.

⁽²⁾ For the year ended December 31, 2011, we recorded litigation-related and certain merger-related after-tax expenses of $29.4 million.

⁽³⁾ For the year ended December 31, 2013, we recorded certain merger-related after-tax expenses of $71.9 million.

⁽⁴⁾ For the nine months ended September 30, 2013, we recorded certain merger-related after-tax expenses of $4.1 million.

⁽⁵⁾ For the three months ended September 30, 2014, we recorded certain merger-related after-tax expenses of $18.3 million.

We may issue from time to time, in one or more offerings, the following securities:

We will set forth in the applicable prospectus supplement a description of the common stock, preferred stock, debt securities, warrants, depositary shares, subscription rights, stock purchase contracts, stock purchase units or stock appreciation rights that may be offered under this prospectus. The terms of the offering of securities, the initial offering price and net proceeds to us will be contained in the prospectus supplement and other filings relating to such offering.

We may sell the securities covered by this prospectus in one or more of the following ways from time to time, including without limitation:

A prospectus supplement with respect to each series of securities will state the terms of the offering of the securities, including:

If we use underwriters or dealers in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including:

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Remarketing firms, agents, underwriters and dealers may be entitled under agreements which they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

There is currently no market for any of the offered securities, other than the common stock which is listed on the NYSE and the CSX. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We have no current plans for listing of any of the preferred stock, debt securities, warrants, depositary shares, subscription rights, stock purchase contracts, stock purchase units, or stock appreciation rights on any securities exchange; any such listing with respect to any particular security will be described in the applicable prospectus supplement or pricing supplement, as the case may be.

Selling security holders are persons or entities that, directly or indirectly, have acquired or will from time to time acquire from us, common stock, preferred stock, debt securities, warrants, depositary shares, subscription rights, stock purchase contracts, stock purchase units, or stock appreciation rights in various private transactions. Such selling security holders may be parties to registration rights agreements with us, or we otherwise may have agreed or will agree to register their securities for resale. The initial purchasers of our securities, as well as their transferees, pledges, donees or successors, all of whom we refer to as “selling security holders,” may from time to time offer and sell the securities pursuant to this prospectus and any applicable prospectus supplement.

Information about selling security holders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment, and in filings we make with the SEC under the Securities Exchange Act of 1934, as amended, which we incorporate by reference into this registration statement.

In connection with particular offerings of our securities in the future, and unless otherwise indicated in the applicable prospectus supplement, the validity of such securities will be passed upon for Stifel Financial Corp. by Bryan Cave LLP, St. Louis, Missouri.

The consolidated financial statements of Stifel Financial Corp. appearing in Stifel Financial Corp.’s Annual Report on Form 10-K for the year ended December 31, 2013, and the effectiveness of Stifel Financial Corp.’s internal control over financial reporting as of December 31, 2013 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.
