(the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom, Europe, and Canada. Our company’s principal customers are individual investors, corporations, municipalities, and institutions. Basis of Presentation The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe, Bruyette & Woods, Inc., Stifel Bancorp, Inc.

Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”).

In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise noted) necessary to fairly present our financial position, results of operations and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and the notes thereto in our Annual Report on Form 10-K for the year ended December 31, 2022 on file with the SEC. Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material. Consolidation Policies The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. We have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. Under our current consolidation policy we consolidate those entities where we have the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity. We determine whether we are the primary beneficiary of a variable interest entity (“VIE”) by performing an analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. We reassess our evaluation of whether an entity is a VIE when certain reconsideration events occur. We reassess our determination of whether we are the primary beneficiary of a VIE on an ongoing basis based on current facts and circumstances. See Note 25 for additional information on VIEs.

Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Pronouncements	NOTE 2 – New Accounting Pronouncements Recently Adopted Accounting Guidance Financial Instruments – Credit Losses In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, “Financial Instruments – Credit Losses (ASC 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures,” which eliminates the accounting guidance for TDRs, now requiring an entity to determine whether a modification results in a new loan or a continuation of an existing loan, as well as expanding disclosures related to modifications and requires disclosure of current period gross write-offs of financing receivables within the vintage disclosures table. The accounting update is effective for interim and annual periods beginning after December 15, 2022 (January 1, 2023, for our company), and early adoption is permitted. The adoption of the accounting update did not have a material impact on our consolidated financial statements. Recently Issued Accounting Guidance Fair Value Measurement In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (ASU 2022-03), an update to ASC Topic 820 – Fair Value Measurement. The amendments in ASU 2022-03 clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The amendments require new disclosures related to equity securities subject to contractual sale restrictions, including the fair value of such equity securities, the nature and remaining duration of the corresponding restrictions and any circumstances that could cause a lapse in the restrictions. The amendments are effective for annual reporting periods beginning after December 15, 2023 (January 1, 2024, for our company) and for the interim periods within those annual reporting periods. Early adoption is permitted, including in an interim period. We are currently evaluating the impact that the accounting update will have on our consolidated financial statements. Leases In March 2023, the FASB issued ASU 2023-01, “Leases (Topic 842): Common Control Arrangements,” which requires entities to classify and account for leases with related parties on the basis of legally enforceable terms and conditions of the arrangement. The accounting update is effective for interim and annual periods beginning after December 15, 2023 (January 1, 2024, for our company), and early adoption is permitted. We are currently evaluating the impact that the accounting update will have on our consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 4 – Fair Value Measurements We measure certain financial assets and liabilities at fair value on a recurring basis, including financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. We generally utilize third-party pricing services to value Level 1 and Level 2 available-for-sale investment securities, as well as certain derivatives designated as cash flow hedges. We review the methodologies and assumptions used by the third-party pricing services and evaluate the values provided, principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models using available third-party market data. We may occasionally adjust certain values provided by the third-party pricing service when we believe, as the result of our review, that the adjusted price most appropriately reflects the fair value of the particular security. Following are descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value. The descriptions include an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Financial Instruments Owned and Available-For-Sale Securities When available, the fair value of financial instruments is based on quoted prices in active markets and reported in Level 1. Level 1 financial instruments include highly liquid instruments with quoted prices, such as U.S. government securities, corporate fixed income securities, and equity securities listed in active markets. If quoted prices are not available for identical instruments, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include U.S. government agency securities, mortgage-backed securities, fixed income and equity securities infrequently traded, state and municipal securities, asset-backed securities, and non-agency mortgage-backed securities and sovereign debt securities, included in other in the table below. We have identified Level 3 financial instruments to include certain asset-backed securities and syndicated loans, included in other in the table below. Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. Investments Investments carried at fair value primarily include corporate equity securities, auction-rate securities (“ARS”), and private company investments. Corporate equity securities are primarily valued based on quoted prices in active markets and reported in Level 1. ARS are primarily valued based upon our expectations of issuer redemptions and using internal discounted cash flow models that utilize unobservable inputs. ARS are reported as Level 3 assets. Private company investments are primarily valued based upon internally developed models. These valuations require significant management judgment due to the absence of quoted market prices, the inherent lack of liquidity, and their long-term nature. Typically, the initial costs of these investments are considered to represent fair market value, as such amounts are negotiated between willing market participants. Private company investments are primarily reported as Level 3 assets. Investments at fair value include investments in funds, including certain money market funds that are measured at net asset value (“NAV”). The Company uses NAV to measure the fair value of its fund investments when (i) the fund investment does not have a readily determinable fair value and (ii) the NAV of the investment fund is calculated in a manner consistent with the measurement principles of investment company accounting, including measurement of the underlying investments at fair value. The Company’s investments in funds measured at NAV include partnership interests, mutual funds, money market funds, and private equity funds. Private equity funds primarily invest in a broad range of industries worldwide in a variety of situations, including leveraged buyouts, recapitalizations, growth investments and distressed investments. The private equity funds are primarily closed-end funds in which the Company’s investments are generally not eligible for redemption. Distributions will be received from these funds as the underlying assets are liquidated or distributed. The general and limited partnership interests in investment partnerships were primarily valued based upon NAVs received from third-party fund managers. The various partnerships are investment companies, which record their underlying investments at fair value based on fair value policies established by management of the underlying fund. Fair value policies at the underlying fund generally require the funds to utilize pricing/valuation information, including independent appraisals, from third-party sources. However, in some instances, current valuation information for illiquid securities or securities in markets that are not active may not be available from any third-party source or fund management may conclude that the valuations that are available from third-party sources are not reliable. In these instances, fund management may perform model-based analytical valuations that may be used as an input to value these investments. The table below presents the fair value of our investments in, and unfunded commitments to, funds that are measured at NAV as of June 30, 2023 and December 31, 2022 (in thousands) : June 30, 2023 December 31, 2022 Fair value of investments Unfunded commitments Fair value of investments Unfunded commitments Partnership interests $ 21,103 $ 7,846 $ 18,817 $ 9,853 Mutual funds 3,373 — 4,728 — Money market funds 791 — 1,650 — Private equity funds 416 1,181 417 1,181 Total $ 25,683 $ 9,027 $ 25,612 $ 11,034 Financial Instruments Sold, But Not Yet Purchased Financial instruments sold, but not purchased, recorded at fair value based on quoted prices in active markets and other observable market data include highly liquid instruments with quoted prices, such as U.S. government securities, and fixed income and equity securities listed in active markets, which are reported as Level 1. If quoted prices are not available, fair values are obtained from pricing services, broker quotes, or other model-based valuation techniques with observable inputs, such as the present value of estimated cash flows, and reported as Level 2. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include U.S. government agency securities, agency mortgage-backed securities not actively traded, fixed income securities, and state and municipal securities. We have identified Level 3 financial instruments to include syndicated loans, included in other in the table below. Level 3 financial instruments have little to no pricing observability as of the report date. These financial instruments do not have active two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. Derivatives Derivatives are valued using quoted market prices for identical instruments when available or observable inputs from forward and futures yield curves. The valuation models used require market observable inputs, including contractual terms, market prices, yield curves, credit curves, and measures of volatility. We have classified our derivatives as Level 2. The counterparties to most of our company’s derivative transactions represent regulated banks, bank holding companies, and derivative clearing houses. Management has determined that the counterparty credit risk associated with its derivative transactions is not significant. Accordingly, the recorded fair values for these transactions have not been adjusted to reflect counterparty credit risk.

The tables above do not present Level 1 or Level 2 valued assets or liabilities. The changes in unrealized gains/(losses) recorded in earnings for the three and six months ended June 30, 2023, relating to Level 3 assets still held at June 30, 2023, were immaterial. The fair value of certain Level 3 assets was determined using various methodologies, as appropriate, including third-party pricing vendors and broker quotes. These inputs are evaluated for reasonableness through various procedures, including due diligence reviews of third-party pricing vendors, variance analyses, consideration of current market environment, and other analytical procedures. The fair value for our auction rate securities was determined using an income approach based on an internally developed discounted cash flow model. The discounted cash flow model utilizes two significant unobservable inputs: discount rate and workout period. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. On an ongoing basis, management verifies the fair value by reviewing the appropriateness of the discounted cash flow model and its significant inputs.

Financial Assets Securities Purchased Under Agreements to Resell Securities purchased under agreements to resell are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at June 30, 2023 and December 31, 2022 approximate fair value due to their short-term nature. Held-to-Maturity Securities Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include asset-backed securities, consisting of collateralized loan obligation securities and student loan ARS. The estimated fair value, included in the above table, is determined using several factors; however, primary weight is given to discounted cash flow modeling techniques that incorporated an estimated discount rate based upon recent observable debt security issuances with similar characteristics. Bank Loans The fair values of mortgage loans and commercial loans were estimated using a discounted cash flow method, a form of the income approach. Discount rates were determined considering rates at which similar portfolios of loans, with similar remaining maturities, would be made and considering liquidity spreads applicable to each loan portfolio based on the secondary market. Loans Held for Sale Loans held for sale consist of fixed-rate and adjustable-rate residential real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Financial Liabilities Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. The carrying values at June 30, 2023 and December 31, 2022 approximate fair value due to the short-term nature. Bank Deposits The fair value of interest-bearing deposits, including certificates of deposits, demand deposits, savings, and checking accounts, was calculated by discounting the future cash flows using discount rates based on the replacement cost of funding of similar structures and terms. Senior Notes The fair value of our senior notes is estimated based upon quoted market prices. Debentures to Stifel Financial Capital Trusts The fair value of our trust preferred securities is based on the discounted value of contractual cash flows. We have assumed a discount rate based on similar type debt instruments. These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates.

Receivables [Abstract]
Bank Loans	NOTE 7 – Bank Loans Our loan portfolio consists primarily of the following segments: Commercial and industrial (C&I). C&I loans primarily include commercial and industrial lending used for general corporate purposes, working capital and liquidity, and “event-driven.” “Event-driven” loans support client merger, acquisition or recapitalization activities. C&I lending is structured as revolving lines of credit, letter of credit facilities, term loans and bridge loans. Risk factors considered in determining the allowance for corporate loans include the borrower’s financial strength, seniority of the loan, collateral type, leverage, volatility of collateral value, debt cushion, and covenants. Fund banking. Fund banking loans primarily include capital call lines of credit, also known as subscription lines of credit. These credit facilities are used by closed-end private investment funds (“Fund”) that have raised capital commitments from limited partners to effectively manage the Fund’s cash and bridge timing between the Fund’s investments and capital calls. The lines of credit are collateralized by a pledge of the limited partner’s contractually callable capital and the general partner’s right to call such capital as permitted in the Fund’s partnership agreement. Securities-based loans. Securities-based loans allow clients to borrow money against the value of qualifying securities for any suitable purpose other than purchasing, trading, or carrying securities or refinancing margin debt. The majority of consumer loans are structured as revolving lines of credit and letter of credit facilities and are primarily offered through Stifel’s Pledged Asset (“SPA”) program. The allowance methodology for securities-based lending considers the collateral type underlying the loan, including the liquidity and trading volume of the collateral, position concentration and other borrower specific factors such as personal guarantees. Real Estate. Real estate loans include residential real estate non-conforming loans, residential real estate conforming loans, commercial real estate, and home equity lines of credit. The allowance methodology related to real estate loans considers several factors, including, but not limited to, loan-to-value ratio, FICO score, home price index, delinquency status, credit limits, and utilization rates. Construction and land. Short-term loans used to finance the development of a real estate project. Other. Other loans include consumer and credit card lending.

Credit quality indicators As of June 30, 2023, bank loans were primarily extended to non-investment grade borrowers. Substantially all of these loans align with the U.S. Federal bank regulatory agencies’ definition of Pass. Loans meet the definition of Pass when they are performing and do not demonstrate adverse characteristics that are likely to result in a credit loss. A loan is determined to be impaired when principal or interest becomes 90 days past due or when collection becomes uncertain. At the time a loan is determined to be impaired, the accrual of interest and amortization of deferred loan origination fees is discontinued (“nonaccrual status”), and any accrued and unpaid interest income is reversed. We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk. Trends in delinquency ratios are an indicator, among other considerations, of credit risk within our loan portfolio. The level of nonperforming assets represents another indicator of the potential for future credit losses. Accordingly, key metrics we track and use in evaluating the credit quality of our loan portfolio include delinquency and nonperforming asset rates, as well as charge-off rates and our internal risk ratings of the loan portfolio. In general, we are a secured lender. At June 30, 2023 and December 31, 2022, 97.2 % and 97.5 % of our loan portfolio was collateralized, respectively. Collateral is required in accordance with the normal credit evaluation process based upon the creditworthiness of the customer and the credit risk associated with the particular transaction. The Company uses the following definitions for risk ratings: Pass. A credit exposure rated pass has a continued expectation of timely repayment, all obligations of the borrower are current, and the obligor complies with material terms and conditions of the lending agreement. Special Mention. Extensions of credit that have potential weakness that deserve management’s close attention, and if left uncorrected may, at some future date, result in the deterioration of the repayment prospects or collateral position. Substandard. Obligor has a well-defined weakness that jeopardizes the repayment of the debt and has a high probability of payment default with the distinct possibility that the Company will sustain some loss if noted deficiencies are not corrected. Doubtful. Inherent weakness in the exposure makes the collection or repayment in full, based on existing facts, conditions and circumstances, highly improbable, and the amount of loss is uncertain. Substandard loans are regularly reviewed for impairment. Doubtful loans are considered impaired. When a loan is impaired the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, or as a practical expedient, the observable market price of the loan or the fair value of the collateral if the loan is collateral dependent. Based on the most recent analysis performed, the risk category of our loan portfolio was as follows (in thousands) : As of June 30, 2023 Pass Special Mention Substandard Doubtful Total Residential real estate $ 7,706,547 $ 312 $ 927 $ 720 $ 7,708,506 Commercial and industrial 4,298,705 17,619 145,824 8,883 4,471,031 Fund banking 4,349,541 — — — 4,349,541 Securities-based loans 2,399,325 — — 3 2,399,328 Construction and land 772,571 — — — 772,571 Commercial real estate 577,777 60,000 39,744 — 677,521 Home equity lines of credit 110,369 65 22 310 110,766 Other 43,672 11 — 20 43,703 Total $ 20,258,507 $ 78,007 $ 186,517 $ 9,936 $ 20,532,967 As of December 31, 2022 Pass Special Mention Substandard Doubtful Total Residential real estate $ 7,370,717 $ 266 $ — $ 688 $ 7,371,671 Commercial and industrial 4,743,290 87,761 56,899 9,226 4,897,176 Fund banking 4,182,641 — — — 4,182,641 Securities-based loans 2,724,548 — — 3 2,724,551 Commercial real estate 655,599 20,000 — — 675,599 Construction and land 593,191 — — — 593,191 Home equity lines of credit 106,954 — — 182 107,136 Other 50,587 — — 6 50,593 Total $ 20,427,527 $ 108,027 $ 56,899 $ 10,105 $ 20,602,558 Term Loans Amortized Cost Basis by Origination Year – June 30, 2023 2023 2022 2021 2020 2019 Prior Revolving Loans Amortized Cost Basis Total Residential real estate: Pass $ 615,464 $ 2,719,320 $ 2,401,583 $ 953,046 $ 425,255 $ 591,879 $ — $ 7,706,547 Special Mention — 312 — — — — — 312 Substandard — 927 — — — — — 927 Doubtful — — — — — 720 — 720 $ 615,464 $ 2,720,559 $ 2,401,583 $ 953,046 $ 425,255 $ 592,599 $ — $ 7,708,506 Commercial and industrial: Pass $ 382,997 $ 1,243,444 $ 1,233,314 $ 259,293 $ 245,865 $ 264,226 $ 669,566 $ 4,298,705 Special Mention — — — — — 9,901 7,718 17,619 Substandard — 15,877 77,106 — 4,064 — 48,777 145,824 Doubtful — — — 433 — 8,450 — 8,883 $ 382,997 $ 1,259,321 $ 1,310,420 $ 259,726 $ 249,929 $ 282,577 $ 726,061 $ 4,471,031 Fund banking: Pass $ — $ 55,267 $ — $ 578 $ — $ — $ 4,293,696 $ 4,349,541 Special Mention — — — — — — — — Substandard — — — — — — — — Doubtful — — — — — — — — $ — $ 55,267 $ — $ 578 $ — $ — $ 4,293,696 $ 4,349,541 Securities-based loans: Pass $ 7,431 $ 30,296 $ 3,100 $ 45,104 $ 27,278 $ 9,294 $ 2,276,822 $ 2,399,325 Special Mention — — — — — — — — Substandard — — — — — — — — Doubtful — — — — — — 3 3 $ 7,431 $ 30,296 $ 3,100 $ 45,104 $ 27,278 $ 9,294 $ 2,276,825 $ 2,399,328 Construction and land: Pass $ 10,009 $ 340,868 $ 172,485 $ 163,348 $ 85,861 $ — $ — $ 772,571 Special Mention — — — — — — — — Substandard — — — — — — — — Doubtful — — — — — — — — $ 10,009 $ 340,868 $ 172,485 $ 163,348 $ 85,861 $ — $ — $ 772,571 Commercial real estate: Pass $ 30,174 $ 356,579 $ 70,105 $ 31,790 $ 20,800 $ 68,329 $ — $ 577,777 Special Mention — 60,000 — — — — — 60,000 Substandard — — 39,744 — — — — 39,744 Doubtful — — — — — — — — $ 30,174 $ 416,579 $ 109,849 $ 31,790 $ 20,800 $ 68,329 $ — $ 677,521 Home equity lines of credit: Pass $ — $ — $ — $ — $ — $ — $ 110,369 $ 110,369 Special Mention — — — — — — 65 65 Substandard — — — — — — 22 22 Doubtful — — — — — — 310 310 $ — $ — $ — $ — $ — $ — $ 110,766 $ 110,766 Other: Pass $ 2,100 $ 3,991 $ — $ 10,000 $ — $ 21,755 $ 5,826 $ 43,672 Special Mention — — — — — — 11 11 Substandard — — — — — — — Doubtful — — — — — — 20 20 $ 2,100 $ 3,991 $ — $ 10,000 $ — $ 21,755 $ 5,857 $ 43,703

On March 1, 2023, the Company acquired Torreya, an independent M&A and private capital advisory firm that serves the global life sciences industry. Consideration for this acquisition consisted of cash from operations. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $ 61.2 million of goodwill and intangible assets in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment. The allocation of the purchase price of Torreya is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Torreya as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Torreya’s business, its employees, and customer base. A significant amount of the goodwill is expected to be deductible for federal income tax purposes. Intangible assets consist of acquired customer relationships, trade names, non-compete agreements, core deposits, and investment banking backlog that are amortized over their contractual or determined useful lives. Intangible assets as of June 30, 2023 and December 31, 2022 were as follows (in thousands) : June 30, 2023 December 31, 2022 Gross Accumulated Amortization Gross Accumulated Amortization Customer relationships $ 227,405 $ 116,189 $ 225,631 $ 109,216 Trade names 30,359 21,625 30,359 20,861 Non-compete agreements 10,071 7,753 9,440 7,158 Core deposits 8,615 7,812 8,615 7,389 Investment banking backlog 8,913 4,965 5,545 4,377 $ 285,363 $ 158,344 $ 279,590 $ 149,001 Amortization expense related to intangible assets was $ 4.6 million and $ 5.5 million for the three months ended June 30, 2023 and 2022, respectively. Amortization expense related to intangible assets was $ 9.1 million and $ 10.6 million for the six months ended June 30, 2023 and 2022, respectively. Amortization expense is included in other operating expenses in the consolidated statements of operations. The weighted-average remaining lives of the following intangible assets at June 30, 2023, are: customer relationships, 10.0 years; trade names, 7.5 years; non-compete agreements, 4.7 years; core deposits, 1.6 years; and investment banking backlog, 5.1 years. We have an intangible asset that is not subject to amortization and is, therefore, not included in the table below. As of June 30, 2023, we expect amortization expense in future periods to be as follows (in thousands) : Fiscal year Remainder of 2023 $ 8,960 2024 17,170 2025 14,952 2026 13,362 2027 11,963 Thereafter 58,494 $ 124,901

Short-Term Debt, Other Disclosure [Abstract]
Borrowings and Federal Home Loan Bank Advances	NOTE 9 – Borrowings and Federal Home Loan Bank Advances Our short-term financing is generally obtained through short-term bank line financing on an uncommitted, secured basis, securities lending arrangements, repurchase agreements, advances from the Federal Home Loan Bank, term loans, and committed bank line financing on an unsecured basis. We borrow from various banks on a demand basis with company-owned and customer securities pledged as collateral. The value of customer-owned securities used as collateral is not reflected in the consolidated statements of financial condition. We also have an unsecured, committed bank line available. Our uncommitted secured lines of credit at June 30, 2023, totaled $ 880.0 million with four banks and are dependent on having appropriate collateral, as determined by the bank agreements, to secure an advance under the line. The availability of our uncommitted lines is subject to approval by the individual banks each time an advance is requested and may be denied. Our peak daily borrowing on our uncommitted secured lines was $ 111.0 million during the six months ended June 30, 2023. 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 June 30, 2023, we had no outstanding balances on our uncommitted secured lines of credit. The Federal Home Loan advances are floating-rate advances. The weighted average interest rates on these advances during the three and six months ended June 30, 2023 was 1.35 % and 4.94 %, respectively. The advances are secured by Stifel Bancorp’s residential mortgage loan portfolio and investment portfolio. The interest rates reset on a daily basis. Stifel Bancorp has the option to prepay these advances without penalty on the interest reset date. At June 30, 2023, there were no Federal Home Loan advances. On May 27, 2021, the Company and Stifel entered into an unsecured revolving credit facility agreement (the “Credit Facility”). The Credit Facility has a maturity date of May 2026 and the lenders include a number of financial institutions. This committed unsecured borrowing facility provides for maximum borrowings of up to $ 500.0 million, with a sublimit of $ 200.0 million for the Company. Stifel may borrow up to $500.0 million under the Credit Facility, depending on the amount of outstanding borrowings of the Company. The interest rates on borrowings under the Credit Facility are variable and based on the Secured Overnight Financing Rate. There were no borrowings outstanding on the Credit Facility as of June 30, 2023.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Guarantees, and Contingencies	NOTE 14 – Commitments, Guarantees, and Contingencies Broker-Dealer Commitments and Guarantees In the normal course of business, we enter into underwriting commitments. Settlement of transactions relating to such underwriting commitments, which were open at June 30, 2023, had no material effect on the consolidated financial statements. As a part of our fixed income public finance operations, we enter into forward commitments to purchase agency mortgage-backed securities. In order to hedge the market interest rate risk to which we would otherwise be exposed between the date of the commitment and date of sale of the mortgage-backed securities, we enter into to be announced (“TBA”) security contracts with investors for generic mortgage-backed security at specific rates and prices to be delivered on settlement dates in the future. We may be subject to loss if the timing of, or the actual amount of, the mortgage-backed security differs significantly from the term and notional amount of the TBA security contract to which we entered. These TBA securities and related purchase commitment are accounted for at fair value. As of June 30, 2023, the fair value of the TBA securities and the estimated fair value of the purchase commitments were $ 66.6 million. We also provide guarantees to securities clearinghouses and exchanges under their standard membership agreement, which requires members to guarantee the performance of other members. Under the agreement, if another member becomes unable to satisfy its obligations to the clearinghouse, other members would be required to meet shortfalls. Our liability under these agreements is not quantifiable and may exceed the cash and securities we have posted as collateral. However, the potential requirement for us to make payments under these arrangements is considered remote. Accordingly, no liability has been recognized for these arrangements. Other Commitments In the ordinary course of business, Stifel Bancorp has commitments to extend credit in the form of commitments to originate loans, standby letters of credit, and lines of credit. See Note 21 in the notes to consolidated financial statements for further details. Concentration of Credit Risk We provide investment, capital-raising, and related services to a diverse group of domestic customers, including governments, corporations, and institutional and individual investors. Our exposure to credit risk associated with the non-performance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile securities markets, credit markets, and regulatory changes. This exposure is measured on an individual customer basis and on a group basis for customers that share similar attributes. To reduce the potential for risk concentrations, counterparty credit limits have been implemented for certain products and are continually monitored in light of changing customer and market conditions. As of June 30, 2023, we did not have significant concentrations of credit risk with any one customer or counterparty, or any group of customers or counterparties.

Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against our company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be. We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations, and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or reasonably possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated. In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters, including the matter described below, the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements. SEC Investigation of Communications Recordkeeping The Company has been contacted by the SEC in connection with an investigation of the Company’s compliance with records preservation requirements for off-channel communications relating to the broker-dealer or investment adviser business activities of the Company using personally owned communications devices and/or messaging platforms that have not been approved by the Company. At this time, based upon currently available information and review with outside counsel, the Company is not able to estimate the outcome of this matter, including the range of possible ultimate resolutions. The Company has also been contacted by the CFTC in connection with an investigation of the use of non-Stifel communications platforms for business-related communications by employees who were associated persons of CFTC registrants. At this time, based upon currently available information and review with outside counsel, the Company is not able to estimate the outcome of this matter, including the range of possible ultimate resolutions.

Regulatory Capital Requirements

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital Requirements	NOTE 16 – Regulatory Capital Requirements We operate in a highly regulated environment and are subject to capital requirements, which may limit distributions to our company from its subsidiaries. Distributions from our broker-dealer subsidiaries are subject to net capital rules. A broker-dealer that fails to comply with the SEC’s Uniform Net Capital Rule (Rule 15c3-1) may be subject to disciplinary actions by the SEC and self-regulatory organizations, such as FINRA, including censures, fines, suspension, or expulsion. Stifel has chosen to calculate its net capital under the alternative method, which prescribes that their net capital shall not be less than the greater of $ 1.0 million or two percent of aggregate debit balances (primarily receivables from customers) computed in accordance with the SEC’s Customer Protection Rule (Rule 15c3-3). Our other broker-dealer subsidiaries calculate their net capital under the aggregate indebtedness method, whereby their aggregate indebtedness may not be greater than fifteen times their net capital (as defined). At June 30, 2023, Stifel had net capital of $ 456.5 million, which was 40.4 % of aggregate debit items and $ 433.9 million in excess of its minimum required net capital. At June 30, 2023, all of our other broker-dealer subsidiaries’ net capital exceeded the minimum net capital required under the SEC rule. Our international subsidiary, SNEL, is subject to the regulatory supervision and requirements of the Financial Conduct Authority (“FCA”) in the United Kingdom. At June 30, 2023, our international subsidiary’s capital and reserves were in excess of the financial resources requirement under the rules of the FCA. Our Canadian subsidiary, SNC, is subject to the regulatory supervision and requirements of the Investment Industry Regulatory Organization of Canada (“IIROC”). At June 30, 2023, SNC’s net capital and reserves were in excess of the financial resources requirement under the rules of the IIROC. Our company, as a bank holding company, Stifel Bank & Trust, Stifel Bank, Stifel Trust Company, N.A., and Stifel Trust Company, Delaware, N.A., (collectively, “banking subsidiaries”), are subject to various regulatory capital requirements administered by the Federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our company’s and it’s banking subsidiaries’ financial results. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, our company and its banking subsidiaries must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Our company’s and its banking subsidiaries’ capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Under the Basel III rules, the quantity and quality of regulatory capital increased, a capital conservation buffer was established, selected changes were made to the calculation of risk-weighted assets, and a new ratio, common equity Tier 1 was introduced, all of which are applicable to both our company and its banking subsidiaries. Our company and its banking subsidiaries are required to maintain minimum amounts and ratios of Total and Tier 1 capital (as defined) to risk-weighted assets (as defined), Tier 1 capital to average assets (as defined), and under rules defined in Basel III, Common equity Tier 1 capital to risk-weighted assets. Our company and its banking subsidiaries each calculate these ratios in order to assess compliance with both regulatory requirements and their internal capital policies. At current capital levels, our company and its banking subsidiaries are each categorized as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” our company and its banking subsidiaries must maintain total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios. The amounts and ratios for Stifel Financial Corp., Stifel Bank & Trust, and Stifel Bank as of June 30, 2023 are represented in the tables below (in thousands, except ratios).

Revenues from Contracts with Customers	NOTE 18 – Revenues from Contracts with Customers The following table presents the Company’s total revenues broken out by revenues from contracts with customers and other sources of revenue for the three and six months ended June 30, 2023 and 2022 (in thousands) : Three Months Ended June 30, 2023 2022 Revenues from contracts with customers: Commissions $ 165,358 $ 186,681 Investment banking 166,825 271,075 Asset management 320,264 331,264 Other 1,380 1,533 Total revenue from contracts with customers 653,827 790,553 Other sources of revenue: Interest 482,770 212,754 Principal transactions 105,700 125,603 Other ( 486 ) ( 3,450 ) Total revenues $ 1,241,811 $ 1,125,460 Six Months Ended June 30, 2023 2022 Revenues from contracts with customers: Commissions $ 334,908 $ 382,590 Investment banking 378,704 525,921 Asset management 635,833 672,900 Other 2,607 3,708 Total revenue from contracts with customers 1,352,052 1,585,119 Other sources of revenue: Interest 934,334 378,189 Principal transactions 221,222 284,873 Other ( 4,006 ) 3,263 Total revenues $ 2,503,602 $ 2,251,444 Revenue from contracts with customers is recognized when, or as, we satisfy our performance obligations by transferring the promised services to the customers. A service is transferred to a customer when, or as, the customer obtains control of that service. A performance obligation may be satisfied over time or at a point in time. Revenue from a performance obligation satisfied over time is recognized by measuring our progress in satisfying the performance obligation in a manner that depicts the transfer of the services to the customer. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that we determine the customer obtains control over the promised service. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for those promised services (i.e., the “transaction price”). In determining the transaction price, we consider multiple factors, including the effects of variable consideration. Variable consideration is included in the transaction price only to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainties with respect to the amount are resolved. In determining when to include variable consideration in the transaction price, we consider the range of possible outcomes, the predictive value of our past experiences, the time period of when uncertainties expect to be resolved and the amount of consideration that is susceptible to factors outside of our influence, such as market volatility or the judgment and actions of third parties. The following provides detailed information on the recognition of our revenues from contracts with customers: Commissions. We earn commission revenue by executing, settling, and clearing transactions for clients primarily in OTC and listed equity securities, insurance products, and options. Trade execution and clearing and custody services, when provided together, represent a single performance obligation as the services are not separately identifiable in the context of the contract. Commission revenues associated with combined trade execution and clearing and custody services, as well as trade execution services on a standalone basis, are recognized at a point in time on trade-date. Commission revenues are generally paid on settlement date and we record a receivable between trade-date and payment on settlement date. Investment Banking. We provide our clients with a full range of capital markets and financial advisory services. Capital markets services include underwriting and placement agent services in both the equity and debt capital markets, including private equity placements, initial public offerings, follow-on offerings, underwriting and distributing public and private debt. Capital-raising revenues are recognized at a point in time on trade-date, as the client obtains the control and benefit of the capital markets offering at that point. Costs associated with capital-raising transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded, and are recorded on a gross basis within other operating expenses in the consolidated statements of operations as we are acting as a principal in the arrangement. Any expenses reimbursed by our clients are recognized as investment banking revenues. Revenues from financial advisory services primarily consist of fees generated in connection with merger, acquisition and restructuring transactions. Advisory revenues from mergers and acquisitions engagements are recognized at a point in time when the related transaction is completed, as the performance obligation is to successfully broker a specific transaction. Fees received prior to the completion of the transaction are deferred within accounts payable and accrued expenses on the consolidated statements of financial condition. Advisory revenues from restructuring engagements are recognized over time using a time elapsed measure of progress as our clients simultaneously receive and consume the benefits of those services as they are provided. A significant portion of the fees we receive for our advisory services are considered variable as they are contingent upon a future event (e.g., completion of a transaction or third party emergence from bankruptcy) and are excluded from the transaction price until the uncertainty associated with the variable consideration is subsequently resolved, which is expected to occur upon achievement of the specified milestone. Payment for advisory services are generally due promptly upon completion of a specified milestone or, for retainer fees, periodically over the course of the engagement. We recognize a receivable between the date of completion of the milestone and payment by the customer. Expenses associated with investment banking advisory engagements are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at the same time as the associated expense. All other investment banking advisory related expenses, including expenses incurred related to restructuring assignments, are expensed as incurred. All investment banking advisory expenses are recognized within other operating expenses on the consolidated statements of operations and any expenses reimbursed by our clients are recognized as investment banking revenues. Asset Management Fees. We earn management and performance fees in connection with investment advisory services provided to institutional and individual clients. Investment advisory fees are charged based on the value of assets in fee-based accounts and are affected by changes in the balances of client assets due to market fluctuations and levels of net new client assets. Fees are charged either in advance based on fixed rates applied to the value of the customers’ account at the beginning of the period or periodically based on contracted rates and account performance. Contracts can be terminated at any time with no incremental payments due to our company upon termination. If the contract is terminated by the customer fees are prorated for the period and fees charged for the post termination period are refundable to the customer.

See Note 22 for further break-out of revenues by geography. Information on Remaining Performance Obligations and Revenue Recognized From Past Performance We do not disclose information about remaining performance obligations pertaining to contracts that have an original expected duration of one year or less. The transaction price allocated to remaining unsatisfied or partially unsatisfied performance obligations with an original expected duration exceeding one year was not material at June 30, 2023. Investment banking advisory revenues that are contingent upon completion of a specific milestone and fees associated with certain distribution services are also excluded as the fees are considered variable and not included in the transaction price at June 30, 2023. Contract Balances The timing of our revenue recognition may differ from the timing of payment by our customers. We record a receivable when revenue is recognized prior to payment and we have an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, we record deferred revenue until the performance obligations are satisfied. We had receivables related to revenues from contracts with customers of $ 155.0 million and $ 141.2 million at June 30, 2023 and December 31, 2022, respectively, in other assets in the consolidated statements of financial condition. We had no significant impairments related to these receivables during the six months ended June 30, 2023. Our deferred revenue primarily relates to retainer fees received in investment banking advisory engagements where the performance obligation has not yet been satisfied. Deferred revenue at June 30, 2023 and December 31, 2022 was $ 22.3 million and $ 12.8 million, respectively, and is included in accounts payable and accrued expenses in the consolidated statements of financial condition.

Share-Based Payment Arrangement, Recognized Amount [Abstract]
Employee Incentive, Deferred Compensation, and Retirement Plans	NOTE 20 – Employee Incentive, Deferred Compensation, and Retirement Plans We maintain an incentive stock plan and a wealth accumulation plan (“the Plan”) that provides for the granting of stock options, stock appreciation rights, restricted stock, performance awards, stock units, and debentures (collectively, “deferred awards”) to our associates. We are permitted to issue new shares under all stock award plans approved by shareholders or to reissue our treasury shares. Stock awards issued under our company’s incentive stock plan are granted at market value at the date of grant. Our deferred awards generally vest ratably over a one - to ten-year vesting period. Our stock-based compensation plans are administered by the Compensation Committee of the Board of Directors (“Compensation Committee”), which has the authority to interpret the plans, determine to whom awards may be granted under the plans, and determine the terms of each award. According to the incentive stock plan, we are authorized to grant an additional 5.1 million shares at June 30, 2023. Expense associated with our stock-based compensation, included in compensation and benefits expense in the consolidated statements of operations for our company’s incentive stock award plan was $ 38.1 million and $ 34.8 million for the three months ended June 30, 2023 and 2022, respectively, and $ 67.7 million and $ 67.7 million for the six months ended June 30, 2023 and 2022, respectively. Expense associated with our debentures, included in compensation and benefits expense in the consolidated statements of operations was $ 27.3 million and $ 24.4 million for the three months ended June 30, 2023 and 2022, respectively, and $ 51.2 million and $ 44.3 million for the six months ended June 30, 2023 and 2022, respectively. Deferred Awards A restricted stock unit represents the right to receive a share of the Company’s common stock at a designated time in the future without cash payment by the associate and is issued in lieu of cash incentive, principally for deferred compensation and employee retention plans. The restricted stock units vest on an annual basis over the next one to ten years and are distributable, if vested, at future specified dates. Restricted stock awards are restricted as to sale or disposition. These restrictions lapse over the next one to three years. The Company grants Performance-based Restricted Stock Units (“PRSUs”) to certain of its executive officers. Under the terms of the grants, the number of PRSUs that will vest and convert to shares will be based on the Company’s achievement of the pre-determined performance objectives during the performance period. The PRSUs will be measured over a four-year performance period and vested over a five-year period. Any resulting delivery of shares for PRSUs granted as part of compensation will occur after four years for 80 % of the earned award, and in the fifth year for the remaining 20 % of the earned award. The number of shares converted has the potential to range from 0 % to 200 % based on how the Company performs during the performance period. Compensation expense is amortized over the service period based on the fair value of the deferred award on the grant date. The Company’s pre-determined performance objectives must be met for the awards to vest. Associates forfeit unvested deferred awards upon termination of employment with a corresponding reversal of compensation expense. Certain deferred awards may continue to vest under certain circumstances as described in the Plan. At June 30, 2023, the total number of restricted stock units, PRSUs, and restricted stock awards outstanding was 16.2 million, of which 13.9 million were unvested. At June 30, 2023, there was unrecognized compensation cost for deferred awards of approximately $ 782.7 million, which is expected to be recognized over a weighted-average period of 2.5 years. Deferred Compensation Plans The Plan is provided to certain revenue producers, officers, and key administrative associates, whereby a certain percentage of their incentive compensation is deferred as defined by the Plan into company stock units, restricted stock, and debentures. Participants may elect to defer a portion of their incentive compensation. Deferred awards generally vest over a one - to ten-year period and are distributable upon vesting or at future specified dates. Deferred compensation costs are amortized on a straight-line basis over the vesting period. Elective deferrals are 100 % vested. Additionally, the Plan allows Stifel financial advisors who achieve certain levels of production the option to defer a certain percentage of their gross commissions. As stipulated by the Plan, the financial advisors will defer 5 % of their gross commissions. The mandatory deferral is split between company restricted stock units and debentures. They have the option to defer an additional 1 % of gross commissions into company stock units. In addition, certain revenue producers, upon joining the Company, may receive company stock units in lieu of transition cash payments. Deferred compensation related to these awards generally vests over a one - to eight-year period. Deferred compensation costs are amortized on a straight-line basis over the deferral period. Profit Sharing Plan Eligible U.S. associates of the Company who have met certain service requirements may participate in the Stifel Financial Corp. Profit Sharing 401(k) Plan (the “401(k) Plan”). Associates are permitted within limitations imposed by tax law to make pre-tax contributions to the 401(k) Plan. We may match certain associate contributions or make additional contributions to the 401(k) Plan at our discretion. Our contributions to the 401(k) Plan, included in compensation and benefits in the consolidated statements of operations, were $ 4.3 million and $ 4.4 million for the three months ended June 30, 2023 and 2022, respectively and $ 8.9 million and $ 7.9 million for the six months ended June 30, 2023 and 2022, respectively.

Off-Balance Sheet Credit Risk

Off-Balance Sheet Credit Risk	6 Months Ended
	Jun. 30, 2023
Concentration Risks, Types, No Concentration Percentage [Abstract]
Off-Balance Sheet Credit Risk	NOTE 21 – Off-Balance Sheet Credit Risk In the normal course of business, we execute, settle, and finance customer and proprietary securities transactions. These activities expose our company to off-balance sheet risk in the event that customers or other parties fail to satisfy their obligations. In accordance with industry practice, securities transactions generally settle within two business days after trade date. Should a customer or broker fail to deliver cash or securities as agreed, we may be required to purchase or sell securities at unfavorable market prices. We borrow and lend securities to facilitate the settlement process and finance transactions, utilizing customer margin securities held as collateral. We monitor the adequacy of collateral levels on a daily basis. We periodically borrow from banks on a collateralized basis, utilizing firm and customer margin securities in compliance with SEC rules. Should the counterparty fail to return customer securities pledged, we are subject to the risk of acquiring the securities at prevailing market prices in order to satisfy our customer obligations. We control our exposure to credit risk by continually monitoring our counterparties’ positions, and where deemed necessary, we may require a deposit of additional collateral and/or a reduction or diversification of positions. Our company sells securities it does not currently own (short sales) and is obligated to subsequently purchase such securities at prevailing market prices. We are exposed to risk of loss if securities prices increase prior to closing the transactions. We control our exposure to price risk from short sales through daily review and setting position and trading limits. We manage our risks associated with the aforementioned transactions through position and credit limits and the continuous monitoring of collateral. Additional collateral is required from customers and other counterparties when appropriate. We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At June 30, 2023 and December 31, 2022, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $ 1.8 billion and $ 1.8 billion, respectively, and the fair value of the collateral that had been sold or repledged was $ 318.3 million and $ 212.0 million, respectively. We enter into interest rate derivative contracts to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are principally used to manage differences in the amount, timing, and duration of our known or expected cash payments related to certain variable-rate affiliated deposits. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk. Derivatives’ notional contract amounts are not reflected as assets or liabilities in the consolidated statements of financial condition. Rather, the market or fair value of the derivative transactions are reported in the consolidated statements of financial condition as other assets or accounts payable and accrued expenses, as applicable. For a complete discussion of our activities related to derivative instruments, see Note 12 in the notes to consolidated financial statements. In the ordinary course of business, Stifel Bancorp has commitments to originate loans, standby letters of credit, and lines of credit. Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established by the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash commitments. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if necessary, is based on the credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate. At June 30, 2023 and December 31, 2022, Stifel Bancorp had outstanding commitments to originate loans aggregating $ 278.8 million and $ 164.6 million, respectively. The commitments extended over varying periods of time, with all commitments at June 30, 2023, scheduled to be disbursed in the following three months. Through Stifel Bancorp, in the normal course of business, we originate residential mortgage loans and sell them to investors. We may be required to repurchase mortgage loans that have been sold to investors in the event there are breaches of certain representations and warranties contained within the sales agreements. We may be required to repurchase mortgage loans that were sold to investors in the event that there was inadequate underwriting or fraud, or in the event that the loans become delinquent shortly after they are originated. We also may be required to indemnify certain purchasers and others against losses they incur in the event of breaches of representations and warranties and in various other circumstances, and the amount of such losses could exceed the repurchase amount of the related loans. Consequently, we may be exposed to credit risk associated with sold loans. Standby letters of credit are irrevocable conditional commitments issued by Stifel Bancorp to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Should Stifel Bancorp be obligated to perform under the standby letters of credit, it may seek recourse from the customer for reimbursement of amounts paid. At June 30, 2023 and December 31, 2022, Stifel Bancorp had outstanding letters of credit totaling $ 26.1 million and $ 22.9 million, respectively. A majority of the standby letters of credit commitments at June 30, 2023, have expiration terms that are less than one year . Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Stifel Bancorp uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. At June 30, 2023 and December 31, 2022, Stifel Bancorp had granted unused lines of credit to commercial and consumer borrowers aggregating $ 6.4 billion and $ 6.1 billion, respectively. We are required to evaluate our loan portfolio for any expected losses with recognition of an allowance for credit losses, when applicable. At June 30, 2023 and December 31, 2022, the expected credit losses for unfunded lending commitments was $ 37.5 million and $ 36.2 million, respectively.

Earnings Per Share [Abstract]
Earnings Per Share ("EPS")	NOTE 23 – Earnings Per Share (“EPS”) Basic EPS is computed by dividing earnings available to common shareholders by the weighted-average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Diluted earnings per share include dilutive stock options and stock units under the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended June 30, 2023 and 2022 (in thousands, except per share data) : Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Net income $ 134,352 $ 160,816 $ 291,891 $ 334,365 Preferred dividends 9,320 9,321 18,640 18,641 Net income available to common shareholders $ 125,032 $ 151,495 $ 273,251 $ 315,724 Shares for basic and diluted calculation: Average shares used in basic computation 107,944 109,083 108,360 109,144 Dilutive effect of stock options and units (1) 5,920 8,317 6,298 8,694 Average shares used in diluted computation 113,864 117,400 114,658 117,838 Earnings per common share: Basic $ 1.16 $ 1.39 $ 2.52 $ 2.89 Diluted $ 1.10 $ 1.29 $ 2.38 $ 2.68 (1) Diluted earnings per share is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Diluted earnings per share include units. For the three and six months ended June 30, 2023 and 2022, the anti-dilutive effect from restricted stock units was immaterial. Cash Dividends During the three and six months ended June 30, 2023, we declared and paid cash dividends of $ 0.36 and $ 0.72 per common share. During the three and six months ended June 30, 2022, we declared and paid cash dividends of $ 0.30 and $ 0.60 per common share.

Equity [Abstract]
Shareholders' Equity	NOTE 24 – Shareholders’ Equity Share Repurchase Program We have an ongoing authorization from the Board of Directors to repurchase our common stock in the open market or in negotiated transactions. At June 30, 2023, the maximum number of shares that may yet be purchased under this plan was 6.1 million. The repurchase program has no expiration date. These purchases may be made on the open market or in privately negotiated transactions, depending upon market conditions and other factors. Repurchased shares may be used to meet obligations under our company’s employee benefit plans and for general corporate purposes. During the three months ended June 30, 2023, we repurchased $ 86.8 million, or 1.5 million shares using existing Board authorizations at an average price of $ 58.21 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes. During the six months ended June 30, 2023, we repurchased $ 181.3 million, or 2.9 million shares using existing Board authorizations at an average price of $ 61.59 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes. During the three and six months ended June 30, 2022, we repurchased $ 30.7 million, or 0.5 million shares using existing Board authorizations at an average price of $ 60.68 per share to meet obligations under our company’s employee benefit plans and for general corporate purposes. Issuance of Common Stock During the six months ended June 30, 2023, we issued 2.5 million shares, which were primarily reissued from treasury. Share issuances were primarily a result of the vesting and conversion transactions under our incentive stock award plans. Issuance of Preferred Stock On July 22, 2021, the Company completed an underwritten registered public offering of $ 300.0 million of 4.50 % Non-Cumulative Perpetual Preferred Stock, Series D, $ 1.00 par value, with a liquidation preference of $ 25,000 per share (equivalent to $ 25 liquidation preference per depositary share). When, as, and if declared by the board of directors of the Company, dividends will be payable at an annual rate of 4.50 %, payable quarterly, in arrears. The Company may redeem the Series D preferred stock at its option, subject to regulatory approval, on or after August 15, 2026. On August 20, 2021, the Company redeemed all of the outstanding 6.25 % Non-Cumulative Perpetual Preferred Stock, Series A. The redemption price was $ 25.00 per depository share plus accrued and unpaid dividends to, but excluding, the date of redemption.

Variable Interest Entities

Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]
Variable Interest Entities	NOTE 25 – Variable Interest Entities Our variable interests in VIEs include debt and equity interests, commitments, certain fees, the establishment of Stifel Financial Capital Trusts, and our issuance of a convertible promissory note. Our involvement with VIEs arises primarily from the following activities: purchases of securities in connection with our trading and secondary market-making activities; retained interests held as a result of securitization activities; and loans to, investments in, and fees from various investment vehicles. Partnership Interests We have formed several non-consolidated investment funds with third-party investors that are typically organized as limited liability companies (“LLCs”) or limited partnerships. These investment vehicles have assets primarily consisting of private and public equity investments. For those funds where we act as the general partner, our company’s economic interest is generally limited to management fee arrangements as stipulated by the fund operating agreements. We have generally provided the third-party investors with rights to terminate the funds or to remove us as the general partner. We have concluded that we are not the primary beneficiary of these VIEs, and therefore, we do not consolidate these entities. Debt and Equity Investments Our exposure to loss is limited to the total of our carrying value. These investment vehicles have net assets, primarily consisting of cash and cash equivalents, aircraft, aircraft engine-related assets, receivables, other assets, and debt. For these investments, our involvement is primarily limited to management fee arrangements as stipulated by the operating agreements. We have concluded that we are not the primary beneficiary of these VIEs, and therefore, we do not consolidate these entities. The following tables present the aggregate assets, liabilities, and our exposure to loss from those VIEs in which we hold a variable interest, but as to which we have concluded we are not the primary beneficiary (in thousands) : June 30, 2023 Aggregate Assets Aggregate Liabilities Our Risk of Loss Debt and Equity Investments $ 395,338 $ 281,112 $ 24,914 Partnership Interests 400,307 2,795 — $ 795,645 $ 283,907 $ 24,914 December 31, 2022 Aggregate Assets Aggregate Liabilities Our Risk of Loss Debt and Equity Investments $ 388,408 $ 296,375 $ 14,776 Partnership Interests 402,703 1,180 — $ 791,111 $ 297,555 $ 14,776 Debenture to Stifel Financial Capital Trusts We have completed private placements of cumulative trust preferred securities through Stifel Financial Capital Trust II, Stifel Financial Capital Trust III, and Stifel Financial Capital Trust IV (collectively, the “Trusts”). The Trusts are non-consolidated wholly owned business trust subsidiaries of our company and were established for the limited purpose of issuing trust securities to third parties and lending the proceeds to our company. The trust preferred securities represent an indirect interest in junior subordinated debentures purchased from our company by the Trusts, and we effectively provide for the full and unconditional guarantee of the securities issued by the Trusts. We make timely payments of interest to the Trusts as required by contractual obligations, which are sufficient to cover payments due on the securities issued by the Trusts, and believe that it is unlikely that any circumstances would occur that would make it necessary for our company to make payments related to these Trusts other than those required under the terms of the debenture agreements and the trust preferred securities agreements. The Trusts were determined to be VIEs because the holders of the equity investment at risk do not have adequate decision-making ability over the Trust’s activities. Our investment in the Trusts is not a variable interest, because equity interests are variable interests only to the extent that the investment is considered to be at risk. Because our investment was funded by the Trusts, it is not considered to be at risk.

Subsequent Events [Abstract]
Subsequent Events	NOTE 26 – Subsequent Events We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Based on the evaluation, we did not identify any recognized and non-recognized subsequent events that would have required adjustment to the consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature Of Operations	Nature of Operations Stifel Financial Corp. (the “Company”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom, Europe, and Canada. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.
Basis Of Presentation	Basis of Presentation The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”), Keefe, Bruyette & Woods, Inc., Stifel Bancorp, Inc. (“Stifel Bancorp”), Stifel Nicolaus Canada Inc. (“SNC”), and Stifel Nicolaus Europe Limited (“SNEL”). Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Pursuant to these rules and regulations, we have omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles. In management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise noted) necessary to fairly present our financial position, results of operations and cash flows. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and the notes thereto in our Annual Report on Form 10-K for the year ended December 31, 2022 on file with the SEC. Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material.
Consolidation Policies	Consolidation Policies The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. We have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. Under our current consolidation policy we consolidate those entities where we have the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity. We determine whether we are the primary beneficiary of a variable interest entity (“VIE”) by performing an analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. We reassess our evaluation of whether an entity is a VIE when certain reconsideration events occur. We reassess our determination of whether we are the primary beneficiary of a VIE on an ongoing basis based on current facts and circumstances. See Note 25 for additional information on VIEs.

Recently Issued Accounting Guidance	Recently Adopted Accounting Guidance Financial Instruments – Credit Losses In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, “Financial Instruments – Credit Losses (ASC 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures,” which eliminates the accounting guidance for TDRs, now requiring an entity to determine whether a modification results in a new loan or a continuation of an existing loan, as well as expanding disclosures related to modifications and requires disclosure of current period gross write-offs of financing receivables within the vintage disclosures table. The accounting update is effective for interim and annual periods beginning after December 15, 2022 (January 1, 2023, for our company), and early adoption is permitted. The adoption of the accounting update did not have a material impact on our consolidated financial statements. Recently Issued Accounting Guidance Fair Value Measurement In June 2022, the FASB issued ASU 2022-03, “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions” (ASU 2022-03), an update to ASC Topic 820 – Fair Value Measurement. The amendments in ASU 2022-03 clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The amendments require new disclosures related to equity securities subject to contractual sale restrictions, including the fair value of such equity securities, the nature and remaining duration of the corresponding restrictions and any circumstances that could cause a lapse in the restrictions. The amendments are effective for annual reporting periods beginning after December 15, 2023 (January 1, 2024, for our company) and for the interim periods within those annual reporting periods. Early adoption is permitted, including in an interim period. We are currently evaluating the impact that the accounting update will have on our consolidated financial statements. Leases In March 2023, the FASB issued ASU 2023-01, “Leases (Topic 842): Common Control Arrangements,” which requires entities to classify and account for leases with related parties on the basis of legally enforceable terms and conditions of the arrangement. The accounting update is effective for interim and annual periods beginning after December 15, 2023 (January 1, 2024, for our company), and early adoption is permitted. We are currently evaluating the impact that the accounting update will have on our consolidated financial statements.
