NEW YORK – November 3, 2021 – BGC Partners, Inc. (Nasdaq: BGCP) ("BGC Partners" or "BGC" or the "Company"), a leading global brokerage and financial technology company, today reported its financial results for the quarter ended September 30, 2021.1 Howard W. Lutnick, Chairman and CEO of BGC Partners: "We are excited about the launch of FMX, our combined U.S. Treasury and Futures electronic marketplace. Leveraging the success of our proven, state-of-the-art Fenics UST platform, our FMX Futures solution will challenge the status quo of the current futures market1. Our clearing agreement with the LCH provides a unique clearing solution across U.S. futures and interest rate swaps. FMX was created in response to our customers' need for an integrated trading and clearing solution, that leverages the world's largest IRS clearing pool at LCH, to provide significant cross margin efficiencies. We continued to grow our Fenics businesses at a strong double-digit pace and we improved all Adjusted Earnings metrics during the quarter. We also repurchased and redeemed over 45 million of our shares and units since the announced sale of our Insurance Brokerage business in May 2021, which closed earlier this week and delivered gross proceeds of $535 million."

Page 2 3 For additional information, please see press release titled "BGC Announces Agreement to Sell its Insurance Brokerage Business to The Ardonagh Group for $500 million" dated May 26, 2021; and press release titled “BGC Completes Sale of Insurance Brokerage Business to The Ardonagh Group" dated November 1, 2021. 4 Financial services revenue excludes Insurance brokerage. 5 Fenics Markets includes the fully electronic portions of BGC’s brokerage businesses, Data, Software and Post-trade revenues that are unrelated to Fenics Growth Platforms, as well as Fenics Integrated revenues. Businesses are categorized as “Fenics Integrated” if they utilize sufficient levels of technology such that significant amounts of their transactions can be, or are, executed without broker intervention and have expected pre-tax Adjusted Earnings margins of at least 25 percent. 6 Fenics Growth Platforms include Fenics UST, Fenics GO, Lucera, Fenics FX and other newer standalone platforms. 7 Central limit order book (“CLOB”) market share is from Greenwich Associates and BGC’s internal estimates. From 3Q 2021 onward, Greenwich Associates updated its methodology for calculating CLOB market share to more accurately reflect CLOB-only trading volumes. 8 BGC received approximately $535 million in gross proceeds, subject to limited post-closing adjustments.

DISCUSSION OF RESULTS BGC generated total revenue of $473.7 million during the third quarter of 2021, an improvement of 4.1 percent from a year ago. Industry-wide trading conditions were mixed during the third quarter, with solid activity across Rates and Energy and Commodities, while Credit volumes were challenged on tighter credit spreads and muted volatility. Fenics net revenue grew 18.7 percent compared to the prior year, and represented a record 22.6 percent of total financial services revenue, increasing from 19.5 percent a year ago3. Fenics revenue contribution and significantly improved front-office productivity drove Adjusted Earnings higher during the quarter.

Revenue performance across the business was as follows9: ▪ Voice / Hybrid, including other revenue, generated revenue of $326.8 million, down 1.4% due to the continued conversion of Voice / Hybrid to Fenics revenue. ▪ Fenics reported third quarter net revenue of $95.3 million, an improvement of 18.7 percent, with a pre- tax Adjusted Earnings margin of 29.5 percent across its Fenics Markets business. BGC's Rates business grew 7.7 percent with particular strength across U.S. government bonds, inflation products, listed rates, and emerging market rates. Equity Derivatives and Cash Equities had strong revenue growth of 15.4 percent, driven by both U.S. and European equity derivatives. Energy and Commodities Page 3 9 Excludes Insurance brokerage unless otherwise stated.

generated 12.8 percent revenue growth, led by BGC's leading environmental brokerage business, and heightened volatility across the energy complex. These improvements were offset by lower Credit revenue. Total brokerage revenue improved 5.7 percent, despite front-office personnel decreasing by 8.6 percent compared to last year. Beginning last year, the Company selectively reduced less productive front-office headcount. These reductions were made alongside increased migration towards Fenics technology solutions, which helped drive average productivity 14.2 percent higher and pre-tax Adjusted Earnings up 15.7 percent compared to a year ago10. FENICS Fenics Revenues (USD millions) 3Q21 3Q20 Change Fenics Markets $84.7 $71.7 18.1% Fenics Growth Platforms 10.6 8.6 23.6% Fenics net revenues $95.3 $80.3 18.7% Technology services (inter-company) 15.8 14.0 12.6% Total Fenics revenues $111.1 $94.3 17.8% Overall Fenics net revenue increased by 18.7 percent in the third quarter, driven by solid double-digit revenue growth across both Fenics Markets and Fenics Growth Platforms. Fenics Growth Platforms revenue improved 23.6 percent from a year ago, driven by revenue growth across Fenics UST, Fenics FX, Fenics GO, and Lucera: ▪ Fenics UST revenue increased over seven-fold, driven by market leading ADV growth, optimization of commercial agreements, new product offerings, and onboarding of new clients. During the third quarter, Fenics UST had ADV growth of over 64 percent, outpacing the overall market. Fenics UST CLOB market share increased from 12 percent a year ago to over 19 percent in the third quarter11. Fenics UST provides the tightest markets, offering prices inside of competing platforms' bid and offer spreads on benchmark U.S. Treasuries. Additionally, Fenics UST launched U.S. Repos on the platform in August. ▪ Fenics FX, an ultra-low latency electronic FX trading platform, generated strong double-digit revenue growth against a challenging trading environment with tempered FX volatility. Fenics FX growth was driven by new clients, and improved fee capture. Its new non-deliverable forwards ("NDF") offering, which launched in the first quarter of 2021, continued to gain traction, with third quarter volumes improving by over 175 percent versus the first quarter of 2021 and over 45 percent quarter-over-quarter. ▪ Lucera, BGC's infrastructure and software business, made significant progress onboarding new institutional and bank clients during the quarter. Winning new clients and expanding existing relationships adds to Lucera's highly recurring and compounding subscription revenue base. Page 4 10 Productivity and Headcount figures exclude Insurance brokerage. 11 Central limit order book (“CLOB”) market share is from Greenwich Associates and BGC’s internal estimates. From 3Q 2021 onward, Greenwich Associates updated its methodology for calculating CLOB market share to more accurately reflect CLOB-only trading volumes.

Additionally, Lucera started offering clients access to cryptocurrency trading venues, leveraging its leading connectivity to exchanges, trading platforms, and custodians. Lucera's cryptocurrency solution is focused on providing clients with world-class infrastructure that offers fully compliant workflows. ▪ Fenics GO, the global options electronic trading platform, more than doubled its revenue from a year ago, driven by the integration of Fenics' existing electronic equities platform MatchBox into its offering. MatchBox is an online platform that automates the trading, booking, and lifecycle management of global equity derivative contracts. The integration of these two electronic platforms provides Fenics GO clients with a comprehensive electronic equity derivatives trading solution. ▪ Fenics' Credit offering, Portfolio Match, a recently deployed session-based, matching platform, continued to gain traction during the quarter with U.S. investment grade credit volumes nearly doubling sequentially from the second quarter of 2021. Portfolio Match currently supports U.S. and European investment grade credit, and European high yield credit. U.S. high yield credit sessions are expected to launch during the fourth quarter of 2021. Fenics Markets revenue improved by 18.1 percent, driven by Rates, FX and Market Data: ▪ Fenics MIDFX, the leading wholesale FX hedging platform, grew its revenue by approximately 44 percent versus the prior year, driven by higher activity across its spot FX and its newer Asian NDF offering, which has continued to gain traction throughout the year. ▪ Fenics Market Data signed 43 new contracts during the third quarter, with the total contracted value increasing by over 200 percent compared to last year. Fenics Market Data has highly recurring and compounding subscription revenue. ▪ Capitalab's NDF Match business, an advanced web-based matching platform that helps clients reduce foreign exchange exposure, grew its volumes by 30 percent, driving double-digit revenue growth compared to a year ago. The Company launched FMX, which combines its leading Fenics UST business and FMX Futures platform. FMX will deliver an integrated trading and clearing solution, utilizing Fenics UST's trading technology and network, combined with the world's largest IRS clearing pool at LCH. BGC's FMX will offer a fully electronic, U.S. Rates cash and futures platform, with a unique clearing solution, providing cross margining offset efficiencies. With respect to value creation, FMX expects key strategic partners to invest in the business and that FMX will open for trading in the middle of 2022. Page 5

Equity-based compensation and allocations of net income to limited partnership units and FPUs, increased 137.8 percent, primarily due to BGC's volume weighted average share price more than doubling compared to the year ago period. Non-compensation expenses under GAAP and Adjusted Earnings decreased by 1.0 percent and 0.9 percent, respectfully, primarily due to lower interest expense, fees to related parties, and other expenses. These expense reductions were partially offset by higher selling and promotion charges, as COVID-19 restrictions have relaxed across many of the major geographies in which BGC operates.

Compared to a year ago, BGC's fully diluted spot share count decreased by 30.9 million shares, or 5.6 percent, which reflected the repurchase and redemption of 45.2 million shares and units since the sale announcement of BGC's Insurance Brokerage business on May 26, 2021. BGC’s fully diluted weighted-average share count under GAAP may differ from the fully diluted weighted- average share count for Adjusted Earnings to avoid anti-dilution in certain periods. This also impacts GAAP net income (loss) for fully diluted shares in such periods. SELECT BALANCE SHEET METRICS14 BGC’s liquidity was $485.6 million as of September 30, 2021 compared with $655.2 million as of year-end 2020. Cash and cash equivalents were $450.8 million as of September 30, 2021 versus $596.3 million as of December 31, 2020, while notes payable and other borrowings were $1,352.5 million compared with $1,315.9 million. Total capital was $703.8 million compared with $832.0 million as of year-end 2020. BGC's balance sheet will further improve due to the $535 million in gross proceeds received on November 1, 2021. A portion of these proceeds have already been used to fully repay the borrowings under the Company's Revolving Credit Agreement, reducing outstanding notes payable and other borrowings. Due to BGC's Insurance Brokerage business being classified as "Held for Sale" as of September 30, 2021, select balance sheet metrics are not fully comparable. Assets related to the Insurance Brokerage business, including cash and cash equivalents are excluded, and reflected within "Assets held for sale", as of September 30, 2021, but not as of December 31, 2020. Additionally, liabilities related to the Insurance Brokerage business are treated as "Liabilities held for sale" on the "Condensed Consolidated Statement of Financial Condition". Page 7 13“Spot” is used interchangeably with the end-of-period share count. 14 The Company considers liquidity to be comprised of the sum of cash and cash equivalents, reverse repurchase agreements (if any), securities owned, and marketable securities, less securities lent out in securities loaned transactions and repurchase agreements (if any). “Cash segregated under regulatory requirements” is not included in liquidity. For more information regarding Liquidity, see the section of this document and/or the Company’s most recent financial results press release titled “Liquidity Analysis”, including any footnotes to the same, for details about how BGC’s non-GAAP results are reconciled to those under GAAP. The Company considers liquidity to be an important metric for determining the amount of cash that is available or that could be readily available to the Company on short notice. The Company defines net debt as notes payable and other borrowings less liquidity. Total capital is defined as redeemable partnership interest, total stockholders' equity and noncontrolling interest in subsidiaries.

OUTLOOK BGC’s revenues, excluding Insurance Brokerage, were approximately 9 percent higher for the first 21 trading days of the fourth quarter of 2021, when compared to the same period in 2020. The fourth quarter of 2020 included $49.1 million of Insurance Brokerage revenue.

The definitions of these terms are below. Adjusted Earnings Defined BGC uses non-GAAP financial measures, including “Adjusted Earnings before noncontrolling interests and taxes” and “Post-tax Adjusted Earnings to fully diluted shareholders”, which are supplemental measures of operating results used by management to evaluate the financial performance of the Company and its consolidated subsidiaries. BGC believes that Adjusted Earnings best reflect the operating earnings generated by the Company on a consolidated basis and are the earnings which management considers when managing its business. As compared with “Income (loss) from operations before income taxes” and “Net income (loss) for fully diluted shares”, both prepared in accordance with GAAP, Adjusted Earnings calculations primarily exclude certain non-cash items and other expenses that generally do not involve the receipt or outlay of cash by the Company and/or which do not dilute existing stockholders. In addition, Adjusted Earnings calculations exclude certain gains and charges that management believes do not best reflect the ordinary results of BGC. Adjusted Earnings is calculated by taking the most comparable GAAP measures and adjusting for certain items with respect to compensation expenses, non-compensation expenses, and other income, as discussed below. Calculations of Compensation Adjustments for Adjusted Earnings and Adjusted EBITDA Treatment of Equity-Based Compensation Line Item for Adjusted Earnings and Adjusted EBITDA The Company’s Adjusted Earnings and Adjusted EBITDA measures exclude all GAAP charges included in the line item “Equity-based compensation and allocations of net income to limited partnership units and FPUs” (or “equity-based compensation” for purposes of defining the Company’s non-GAAP results) as recorded on the Company’s GAAP Consolidated Statements of Operations and GAAP Consolidated Statements of Cash Flows. These GAAP equity-based compensation charges reflect the following items: • Charges with respect to grants of exchangeability, which reflect the right of holders of limited partnership units with no capital accounts, such as LPUs and PSUs, to exchange these units into shares of common stock, or into partnership units with capital accounts, such as HDUs, as well as cash paid with respect to taxes withheld or expected to be owed by the unit holder upon such exchange. The withholding taxes related to the exchange of certain non-exchangeable units without a capital account into either common shares or units with a capital account may be funded by the redemption of preferred units such as PPSUs. • Charges with respect to preferred units. Any preferred units would not be included in the Company’s fully diluted share count because they cannot be made exchangeable into shares of common stock and are entitled only to a fixed distribution. Preferred units are granted in connection with the grant of certain limited partnership units that may be granted exchangeability or redeemed in connection with the grant of shares of common stock at ratios designed to cover any withholding taxes expected to be paid. This is an alternative Page 12

to the common practice among public companies of issuing the gross amount of shares to employees, subject to cashless withholding of shares, to pay applicable withholding taxes. • GAAP equity-based compensation charges with respect to the grant of an offsetting amount of common stock or partnership units with capital accounts in connection with the redemption of non-exchangeable units, including PSUs and LPUs. • Charges related to amortization of RSUs and limited partnership units. • Charges related to grants of equity awards, including common stock or partnership units with capital accounts. • Allocations of net income to limited partnership units and FPUs. Such allocations represent the pro-rata portion of post-tax GAAP earnings available to such unit holders. The amounts of certain quarterly equity-based compensation charges are based upon the Company’s estimate of such expected charges during the annual period, as described further below under “Methodology for Calculating Adjusted Earnings Taxes.” Virtually all of BGC’s key executives and producers have equity or partnership stakes in the Company and its subsidiaries and generally receive deferred equity or limited partnership units as part of their compensation. A significant percentage of BGC’s fully diluted shares are owned by its executives, partners and employees. The Company issues limited partnership units as well as other forms of equity-based compensation, including grants of exchangeability into shares of common stock, to provide liquidity to its employees, to align the interests of its employees and management with those of common stockholders, to help motivate and retain key employees, and to encourage a collaborative culture that drives cross-selling and revenue growth. All share equivalents that are part of the Company’s equity-based compensation program, including REUs, PSUs, LPUs, HDUs, and other units that may be made exchangeable into common stock, as well as RSUs (which are recorded using the treasury stock method), are included in the fully diluted share count when issued or at the beginning of the subsequent quarter after the date of grant. Generally, limited partnership units other than preferred units are expected to be paid a pro-rata distribution based on BGC’s calculation of Adjusted Earnings per fully diluted share. However, out of an abundance of caution and in order to strengthen the Company’s balance sheet due the uncertain macroeconomic conditions with respect to the COVID-19 pandemic, BGC Holdings, L.P. has reduced its distributions of income from the operations of BGC’s businesses to its partners. Compensation charges are also adjusted for certain other cash and non-cash items, including those related to the amortization of GFI employee forgivable loans granted prior to the closing of the January 11, 2016 back- end merger with GFI. Certain Other Compensation-Related Adjustments for Adjusted Earnings BGC also excludes various other GAAP items that management views as not reflective of the Company’s underlying performance in a given period from its calculation of Adjusted Earnings. These may include compensation-related items with respect to cost-saving initiatives, such as severance charges incurred in connection with headcount reductions as part of broad restructuring and/or cost savings plans. Page 13

Calculation of Non-Compensation Adjustments for Adjusted Earnings Adjusted Earnings calculations may also exclude items such as: • Non-cash GAAP charges related to the amortization of intangibles with respect to acquisitions; • Acquisition related costs; • Certain rent charges; • Non-cash GAAP asset impairment charges; and • Various other GAAP items that management views as not reflective of the Company’s underlying performance in a given period, including non-compensation-related charges incurred as part of broad restructuring and/or cost savings plans. Such GAAP items may include charges for exiting leases and/or other long-term contracts as part of cost-saving initiatives, as well as non-cash impairment charges related to assets, goodwill and/or intangibles created from acquisitions. Calculation of Adjustments for Other (income) losses for Adjusted Earnings Adjusted Earnings calculations also exclude certain other non-cash, non-dilutive, and/or non-economic items, which may, in some periods, include: • Gains or losses on divestitures; • Fair value adjustment of investments; • Certain other GAAP items, including gains or losses related to BGC's investments accounted for under the equity method; and • Any unusual, one-time, non-ordinary, or non-recurring gains or losses. Methodology for Calculating Adjusted Earnings Taxes Although Adjusted Earnings are calculated on a pre-tax basis, BGC also reports post-tax Adjusted Earnings to fully diluted shareholders. The Company defines post-tax Adjusted Earnings to fully diluted shareholders as pre-tax Adjusted Earnings reduced by the non-GAAP tax provision described below and net income (loss) attributable to noncontrolling interest for Adjusted Earnings. The Company calculates its tax provision for post-tax Adjusted Earnings using an annual estimate similar to how it accounts for its income tax provision under GAAP. To calculate the quarterly tax provision under GAAP, BGC estimates its full fiscal year GAAP income (loss) from operations before income taxes and noncontrolling interests in subsidiaries and the expected inclusions and deductions for income tax purposes, including expected equity-based compensation during the annual period. The resulting annualized tax rate is applied to BGC’s quarterly GAAP income (loss) from operations before income taxes and noncontrolling interests in subsidiaries. At the end of the annual period, the Company updates its estimate to reflect the actual tax amounts owed for the period. To determine the non-GAAP tax provision, BGC first adjusts pre-tax Adjusted Earnings by recognizing any, and only, amounts for which a tax deduction applies under applicable law. The amounts include charges with respect to equity-based compensation; certain charges related to employee loan forgiveness; certain net operating loss carryforwards when taken for statutory purposes; and certain charges related to tax goodwill amortization. These adjustments may also reflect timing and measurement differences, including treatment of employee loans; changes in the value of units between the dates of grants of exchangeability and the date of Page 14

actual unit exchange; variations in the value of certain deferred tax assets; and liabilities and the different timing of permitted deductions for tax under GAAP and statutory tax requirements. After application of these adjustments, the result is the Company’s taxable income for its pre-tax Adjusted Earnings, to which BGC then applies the statutory tax rates to determine its non-GAAP tax provision. BGC views the effective tax rate on pre-tax Adjusted Earnings as equal to the amount of its non-GAAP tax provision divided by the amount of pre-tax Adjusted Earnings. Generally, the most significant factor affecting this non-GAAP tax provision is the amount of charges relating to equity-based compensation. Because the charges relating to equity-based compensation are deductible in accordance with applicable tax laws, increases in such charges have the effect of lowering the Company’s non- GAAP effective tax rate and thereby increasing its post-tax Adjusted Earnings. BGC incurs income tax expenses based on the location, legal structure and jurisdictional taxing authorities of each of its subsidiaries. Certain of the Company’s entities are taxed as U.S. partnerships and are subject to the Unincorporated Business Tax (“UBT”) in New York City. Any U.S. federal and state income tax liability or benefit related to the partnership income or loss, with the exception of UBT, rests with the unit holders rather than with the partnership entity. The Company’s consolidated financial statements include U.S. federal, state, and local income taxes on the Company’s allocable share of the U.S. results of operations. Outside of the U.S., BGC is expected to operate principally through subsidiary corporations subject to local income taxes. For these reasons, taxes for Adjusted Earnings are expected to be presented to show the tax provision the consolidated Company would expect to pay if 100 percent of earnings were taxed at global corporate rates. Calculations of Pre- and Post-Tax Adjusted Earnings per Share BGC’s pre- and post-tax Adjusted Earnings per share calculations assume either that: • The fully diluted share count includes the shares related to any dilutive instruments, but excludes the associated expense, net of tax, when the impact would be dilutive; or • The fully diluted share count excludes the shares related to these instruments, but includes the associated expense, net of tax. The share count for Adjusted Earnings excludes certain shares and share equivalents expected to be issued in future periods but not yet eligible to receive dividends and/or distributions. Each quarter, the dividend payable to BGC’s stockholders, if any, is expected to be determined by the Company’s Board of Directors with reference to a number of factors, including post-tax Adjusted Earnings per share. BGC may also pay a pro-rata distribution of net income to limited partnership units, as well as to Cantor for its noncontrolling interest. The amount of this net income, and therefore of these payments per unit, would be determined using the above definition of Adjusted Earnings per share on a pre-tax basis. The declaration, payment, timing, and amount of any future dividends payable by the Company will be at the discretion of its Board of Directors using the fully diluted share count. For more information on any share count adjustments, see the table titled “Fully Diluted Weighted-Average Share Count under GAAP and for Adjusted Earnings”. Page 15

Management Rationale for Using Adjusted Earnings BGC’s calculation of Adjusted Earnings excludes the items discussed above because they are either non-cash in nature, because the anticipated benefits from the expenditures are not expected to be fully realized until future periods, or because the Company views results excluding these items as a better reflection of the underlying performance of BGC’s ongoing operations. Management uses Adjusted Earnings in part to help it evaluate, among other things, the overall performance of the Company’s business, to make decisions with respect to the Company’s operations, and to determine the amount of dividends payable to common stockholders and distributions payable to holders of limited partnership units. Dividends payable to common stockholders and distributions payable to holders of limited partnership units are included within “Dividends to stockholders” and “Earnings distributions to limited partnership interests and noncontrolling interests,” respectively, in our unaudited condensed consolidated statements of cash flows. The term “Adjusted Earnings” should not be considered in isolation or as an alternative to GAAP net income (loss). The Company views Adjusted Earnings as a metric that is not indicative of liquidity, or the cash available to fund its operations, but rather as a performance measure. Pre- and post-tax Adjusted Earnings, as well as related measures, are not intended to replace the Company’s presentation of its GAAP financial results. However, management believes that these measures help provide investors with a clearer understanding of BGC’s financial performance and offer useful information to both management and investors regarding certain financial and business trends related to the Company’s financial condition and results of operations. Management believes that the GAAP and Adjusted Earnings measures of financial performance should be considered together. For more information regarding Adjusted Earnings, see the sections of this document and/or the Company’s most recent financial results press release titled “Reconciliation of GAAP Income (Loss) from Operations before Income Taxes to Adjusted Earnings and GAAP Fully Diluted EPS to Post-Tax Adjusted EPS”, including the related footnotes, for details about how BGC’s non-GAAP results are reconciled to those under GAAP. Adjusted EBITDA Defined BGC also provides an additional non-GAAP financial performance measure, “Adjusted EBITDA”, which it defines as GAAP “Net income (loss) available to common stockholders”, adjusted to add back the following items: • Provision (benefit) for income taxes; • Net income (loss) attributable to noncontrolling interest in subsidiaries; • Interest expense; • Fixed asset depreciation and intangible asset amortization; • Equity-based compensation and allocations of net income to limited partnership units and FPUs; • Impairment of long-lived assets; • (Gains) losses on equity method investments; and • Certain other non-cash GAAP items, such as non-cash charges of amortized rents incurred by the Company for its new UK based headquarters. The Company’s management believes that its Adjusted EBITDA measure is useful in evaluating BGC’s operating performance, because the calculation of this measure generally eliminates the effects of financing and income taxes and the accounting effects of capital spending and acquisitions, which would include impairment Page 16

charges of goodwill and intangibles created from acquisitions. Such items may vary for different companies for reasons unrelated to overall operating performance. As a result, the Company’s management uses this measure to evaluate operating performance and for other discretionary purposes. BGC believes that Adjusted EBITDA is useful to investors to assist them in getting a more complete picture of the Company’s financial results and operations. Since BGC’s Adjusted EBITDA is not a recognized measurement under GAAP, investors should use this measure in addition to GAAP measures of net income when analyzing BGC’s operating performance. Because not all companies use identical EBITDA calculations, the Company’s presentation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Furthermore, Adjusted EBITDA is not intended to be a measure of free cash flow or GAAP cash flow from operations because the Company’s Adjusted EBITDA does not consider certain cash requirements, such as tax and debt service payments. For more information regarding Adjusted EBITDA, see the section of this document and/or the Company’s most recent financial results press release titled “Reconciliation of GAAP Net Income (Loss) Available to Common Stockholders to Adjusted EBITDA”, including the footnotes to the same, for details about how BGC’s non-GAAP results are reconciled to those under GAAP. Timing of Outlook for Certain GAAP and Non-GAAP Items BGC anticipates providing forward-looking guidance for GAAP revenues and for certain non-GAAP measures from time to time. However, the Company does not anticipate providing an outlook for other GAAP results. This is because certain GAAP items, which are excluded from Adjusted Earnings and/or Adjusted EBITDA, are difficult to forecast with precision before the end of each period. The Company therefore believes that it is not possible for it to have the required information necessary to forecast GAAP results or to quantitatively reconcile GAAP forecasts to non-GAAP forecasts with sufficient precision without unreasonable efforts. For the same reasons, the Company is unable to address the probable significance of the unavailable information. The relevant items that are difficult to predict on a quarterly and/or annual basis with precision and may materially impact the Company’s GAAP results include, but are not limited, to the following: • Certain equity-based compensation charges that may be determined at the discretion of management throughout and up to the period-end; • Unusual, one-time, non-ordinary, or non-recurring items; • The impact of gains or losses on certain marketable securities, as well as any gains or losses related to associated mark-to- market movements and/or hedging. These items are calculated using period-end closing prices; • Non-cash asset impairment charges, which are calculated and analyzed based on the period-end values of the underlying assets. These amounts may not be known until after period-end; • Acquisitions, dispositions and/or resolutions of litigation, which are fluid and unpredictable in nature. Page 17

Liquidity Defined BGC may also use a non-GAAP measure called “liquidity”. The Company considers liquidity to be comprised of the sum of cash and cash equivalents, reverse repurchase agreements (if any), securities owned, and marketable securities, less securities lent out in securities loaned transactions and repurchase agreements (if any). The Company considers liquidity to be an important metric for determining the amount of cash that is available or that could be readily available to the Company on short notice. For more information regarding Liquidity, see the section of this document and/or the Company’s most recent financial results press release titled “Liquidity Analysis”, including any footnotes to the same, for details about how BGC’s non-GAAP results are reconciled to those under GAAP.

GAAP expenses in the third quarter of 2021 and 2020 included certain one-off costs associated with the cost reduction program of $3.8 million and $1.6 million, respectively. The third quarter of 2021 and 2020 also included certain loan impairments related to the cost reduction program of $1.3 million and $0.9 million, respectively. (3) Includes non-cash GAAP charges related to the amortization of intangibles with respect to acquisitions. (4) GAAP expenses in the third quarter of 2021 and 2020 included Charity Day Contributions of $7.1 million and $1.1 million, respectively, as well as various other GAAP items. Pre-tax Adjusted Earnings in each presented period of 2020 exclude the impact of the employee theft of funds, including penalties and interest, and other immaterial revisions that have been made to previously issued financial statements. The above-referenced items are consistent with BGC’s normal practice of excluding certain GAAP gains and charges from Adjusted Earnings that management believes do not best reflect the ordinary results of the Company, including with respect to non-recurring or unusual gains or losses, as well as resolutions of litigation. (5) Includes non-cash gain of ($0.2) million and a non-cash loss of $1.0 million related to fair value adjustments of investments held by BGC in the third quarter of 2021 and 2020, respectively. (6) For the third quarters of 2021 and 2020, includes non-cash gains of ($1.8) million and ($1.5) million, respectively, related to BGC's investments accounted for under the equity method. The third quarter of 2021 also includes a net gain of ($0.8) million related to various other GAAP items, while the third quarter of 2020 also included a net gain of ($3.3) million related to various other GAAP items. (7) Primarily represents Cantor's pro-rata portion of net income. (8) BGC's GAAP provision for income taxes is calculated based on an annualized methodology. The Company's GAAP provision for income taxes was ($6.7) million and $8.6 million for the third quarters of 2021 and 2020, respectively. The Company includes additional tax-deductible items when calculating the provision for taxes with respect to Adjusted Earnings using an annualized methodology. These include tax-deductions related to equity-based compensation with respect to limited partnership unit exchange, employee loan amortization, and certain net-operating loss carryforwards. The non-GAAP provision for income taxes was adjusted ($10.6) million and $0.7 million for the third quarters of 2021 and 2020, respectively. As a result, the provision for income taxes with respect to Adjusted Earnings was $3.9 million and $7.9 million for the third quarters of 2021 and 2020, respectively. The calculation of taxes for Adjusted Earnings excluded the effect of the 2017 U.S. Tax Cuts and Jobs Act. Note: Certain numbers may not add due to rounding. Page 20
