Item 3. Source and Amount of Funds or Other Consideration

As described in Item 4 below, on December 19, 2017, the Issuer completed its initial public offering (the “IPO”) of 20,000,000 shares of Class A Common Stock. Prior to the IPO, the Issuer was a wholly owned subsidiary of BGC. Upon the closing of the IPO, BGC owned 115,593,786 shares of Class A Common Stock and all of the 15,840,049 issued and outstanding shares of the Issuer’s Class B common stock, par value $0.01 per share (“Class B Common Stock” and, together with Class A Common Stock, “Common Stock”). Shares of Class B Common Stock are convertible into shares of Class A Common Stock on a one-for-one basis, subject to adjustment.

On December 26, 2017, the Issuer completed the sale of an additional 3,000,000 shares of Class A Common Stock pursuant to the underwriters’ exercise in full of their overallotment option granted in connection with the IPO.

On December 13, 2017, prior to the closing of the IPO, BGC, BGC Holdings, L.P. (“BGC Holdings”), BGC Partners, L.P. (“BGC U.S. OpCo”), the Issuer, Newmark Holdings, L.P. (“Newmark Holdings”), Newmark Partners, L.P. (“Newmark OpCo”) and, solely for the provisions listed therein, CFLP and BGC Global Holdings, L.P. (“BGC Global OpCo”) entered into a Separation and Distribution Agreement, dated as of December 13, 2017 (the “Separation and Distribution Agreement”), as may be amended from time to time.

In addition, CFLP received 23,801,347 exchangeable limited partnership units of Newmark Holdings, which may be exchanged for shares of Class A Common Stock or Class B Common Stock, and Mr. Lutnick received 473,073 exchangeable limited partnership units of Newmark Holdings, which may be exchanged for shares of Class A Common Stock, in each case, on a one-for-one basis, subject to adjustment.

On March 7, 2018, BGC, including through its subsidiary BGC U.S. OpCo, purchased 16,606,726 newly issued exchangeable limited partnership units of Newmark Holdings for approximately $242.0 million (the “Investment”). The price per unit was based on the $14.57 closing price of Class A Common Stock on March 6, 2018 as reported on the NASDAQ Global Select Market. These exchangeable limited partnership units may be exchanged for shares of Class A Common Stock or Class B Common Stock on a one-for-one basis, subject to adjustment. BGC and its subsidiaries funded the Investment using the proceeds of its Controlled Equity Offering Class A Common Stock sales program pursuant to the Sales Agreement, dated April 1, 2017, between BGC and Cantor Fitzgerald & Co.

Item 4. Purpose of Transaction

On November 30, 2016, the Issuer submitted a draft registration statement for its IPO to the Securities and Exchange Commission as the initiation of a process to separate BGC’s real estate services business into a separate publicly traded company. On September 8, 2017, the Newmark Group significantly expanded its operations through the completion of the acquisition from Cantor Commercial Real Estate Company, L.P., an affiliate of CFLP, of Berkeley Point Financial LLC, a leading commercial real estate finance company focused on the origination, servicing and sale of multifamily loans through government-sponsored and government-funded loan programs.

On December 13, 2017, prior to the closing of the IPO, BGC, the Issuer, Newmark Holdings and the other parties thereto entered into the Separation and Distribution Agreement to effectuate the Separation. The Separation and Distribution Agreement sets forth the agreements among the parties thereto with respect to the Separation, the IPO, the proportional distribution of interests in Newmark Holdings to holders of interests in BGC Holdings and the Distribution, among other things. The determination of whether, when and how to proceed with the Distribution shall be entirely within the discretion of BGC.

In connection with the Separation, BGC received 115,593,786 shares of Class A Common Stock and 15,840,049 shares of Class B Common Stock, In addition, CFLP received 23,801,347 exchangeable limited partnership units of Newmark Holdings and Mr. Lutnick received 473,073 exchangeable limited partnership units of Newmark Holdings.

On December 19, 2017, the Issuer completed the IPO. Upon the closing of the IPO, BGC owned 115,593,786 shares of Class A Common Stock and all of the 15,840,049 issued and outstanding shares of Class B Common Stock. Shares of Class B Common Stock are convertible into shares of Class A Common Stock. The shares of Common Stock held by each of the Reporting Persons are subject to a customary 180-day lockup restriction entered into with the underwriters of the IPO in connection with the IPO.

On March 7, 2018, BGC, including through its subsidiary BGC U.S. OpCo, purchased 16,606,726 newly issued exchangeable limited partnership units of Newmark Holdings for approximately $242.0 million. The price per unit was based on the $14.57 closing price of Class A Common Stock on March 6, 2018 as reported on the NASDAQ Global Select Market. The Investment was completed pursuant to the terms of the Investment Agreement described in Item 6 below.

The Reporting Persons may, from time to time, depending on market conditions and other factors deemed relevant by such Reporting Persons, acquire additional beneficial ownership of shares of Common Stock or dispose of shares of Common Stock (including, in each case, interests in Newmark Holdings and other interests that are exchangeable or convertible into shares of Common Stock) which such Reporting Persons now own or may hereafter acquire.

Other than as described in this Item 4, none of the Reporting Persons has any current plans or proposals that relate to or that would result in any of the transactions or other matters specified in clauses (a) through (j) of Item 4 of Schedule 13D; provided, that the Reporting Persons may, at any time, review or reconsider their positions with respect to the Issuer and reserve the right to develop such plans or proposals.

Item 6. Contracts, Arrangements, Understandings or Relationships with respect to the Issuer

Separation and Distribution Agreement

The description of certain provisions of the Separation and Distribution Agreement set forth in Item 3 is incorporated by reference herein.

In addition, certain provisions of the Separation and Distribution Agreement provide the Reporting Persons with rights to acquire additional shares of Common Stock under certain circumstances, as described below.

Prior to the Distribution, unless otherwise agreed by BGC, in order for a partner of BGC Holdings to exchange a BGC Holdings exchangeable limited partnership unit into a share of BGC Common Stock pursuant to the BGC Holdings limited partnership agreement, such partner must exchange both one BGC Holdings exchangeable limited partnership unit and a number of Newmark Holdings exchangeable limited partnership units calculated in accordance with the Separation and Distribution Agreement, in order to receive one share of BGC Common Stock. Prior to the Distribution, to the extent that BGC receives any Newmark OpCo limited partnership units as a result of any such exchange of Newmark Holdings exchangeable limited partnership units or otherwise, then BGC will contribute such Newmark OpCo limited partnership units to Newmark in exchange for a number of shares of Common Stock equal to the number of such Newmark OpCo limited partnership units multiplied by the exchange ratio, which is currently one-for-one, subject to adjustment (with the class of shares of Common Stock corresponding to the class of shares of BGC Common Stock issued upon such exchange).

The Separation and Distribution Agreement also provides that any net proceeds received by BGC from any issuances of BGC Common Stock (other than upon exchange of a combination of BGC Holdings exchangeable limited partnership units and Newmark Holdings exchangeable limited partnership units) will be, unless otherwise determined by BGC’s board of directors, contributed to BGC U.S. OpCo, BGC Global OpCo and Newmark OpCo in exchange for (1) a BGC U.S. OpCo limited partnership interest consisting of a number of BGC U.S. OpCo limited partnership units , (2) a BGC Global OpCo limited partnership interest consisting of a number of BGC Global OpCo units and (3) a Newmark OpCo limited partnership interest consisting of a number of Newmark OpCo limited partnership units, in each case calculated in accordance with the Separation and Distribution Agreement. The amount of the net proceeds that will be contributed by BGC to Newmark OpCo for each Newmark OpCo limited partnership unit so issued to BGC Partners will be based on the then-applicable market price for shares of Class A Common Stock. Any such contributions may also be made directly or indirectly into Newmark or Newmark Holdings or through BGC U.S. OpCo, BGC Global OpCo or Newmark OpCo. The remainder of the net proceeds will be contributed by BGC to BGC U.S. OpCo and BGC Global OpCo. BGC’s board of directors will have the right to make any equitable adjustment to the amounts contributed to Newmark OpCo, on the one hand, and BGC U.S. OpCo and BGC Global OpCo, on the other hand, if any events warrant such adjustment. Prior to the

Distribution, to the extent that BGC receives any Newmark OpCo limited partnership units as a result of any such contribution by BGC to Newmark OpCo or purchase by BGC of Newmark OpCo limited partnership units, then in each case, BGC will contribute such Newmark OpCo limited partnership units to Newmark in exchange for a number of shares of Common Stock equal to the number of such Newmark OpCo limited partnership units multiplied by the exchange ratio.

In addition, prior to the Distribution, if BGC exercises its right to purchase from BGC U.S. OpCo and BGC Global OpCo a number of BGC U.S. OpCo limited partnership units and BGC Global OpCo limited partnership units, unless otherwise determined by BGC’s board of directors, BGC will also purchase a number of Newmark OpCo limited partnership units equal to the number of BGC U.S. OpCo limited partnership units so purchased through cash or non-cash consideration for an investment price based on the then-applicable market price for shares of Class A Common Stock. In such case, BGC will contribute such Newmark OpCo limited partnership units to Newmark in exchange for a number of shares of Common Stock equal to the number of such Newmark OpCo limited partnership units multiplied by the exchange ratio.

In the event that Newmark or BGC acquires any additional Newmark OpCo limited partnership units from Newmark OpCo, CFLP would have the right to cause Newmark Holdings to acquire additional Newmark OpCo limited partnership units from Newmark OpCo up to the number of Newmark OpCo units that would preserve CFLP’s relative indirect economic percentage interest in Newmark OpCo compared to Newmark’s and BGC’s aggregate interests immediately prior to the acquisition of such additional Newmark OpCo units by Newmark or BGC, and CFLP would acquire an equivalent number of additional exchangeable limited partnership units of Newmark Holdings, which may be exchanged for shares of Class A Common Stock or Class B Common Stock, to reflect such relative indirect interest.

Pursuant to the Amended and Restated Agreement of Limited Partnership of Newmark Holdings, dated as of December 13, 2017 (the “Newmark Holdings Limited Partnership Agreement”), as may be amended from time to time, CFLP also has certain rights with respect to outstanding founding partner units in Newmark Holdings that were issued in the Separation to founding partners of BGC. CFLP has a right to purchase any Newmark Holdings founding partner units that have not become exchangeable that are redeemed by Newmark Holdings upon termination or bankruptcy of a founding partner or upon mutual consent of the general partner of Newmark Holdings and CFLP. CFLP has the right to purchase such Newmark Holdings founding partner units at a price equal to the lesser of (1) the amount that Newmark Holdings would be required to pay to redeem and purchase such Newmark Holdings founding partner units and (2) the amount equal to (a) the number of units underlying such founding partner units, multiplied by (b) the exchange ratio as of the date of such purchase, multiplied by (c) the then current market price of Class A Common Stock. Any founding partner unit of Newmark Holdings acquired by CFLP, while not exchangeable in the hands of the founding partner absent a determination by CFLP to the contrary, will be exchangeable by CFLP for a number of shares of Class B Common Stock or, at CFLP’s election, shares of Class A Common Stock, in each case, equal to the exchange ratio, on the same basis as the exchangeable limited partnership units of Newmark Holdings held by CFLP. In addition, the Newmark Holdings Limited Partnership Agreement provides that where either current, terminating or terminated partners are permitted by Newmark to exchange any portion of their founding partner units and CFLP consents to such exchangeability, Newmark will offer to CFLP the opportunity for CFLP to purchase the same number of new exchangeable limited partnership units of Newmark Holdings at the price that CFLP would have paid for the founding partner units had Newmark redeemed them.

The exchange ratio is currently one-for-one, but is subject to adjustment, as provided in the Separation and Distribution Agreement.

The foregoing descriptions of certain provisions of the Separation and Distribution Agreement and the Newmark Holdings Limited Partnership Agreement do not purport to be complete and are qualified in its entirety by reference to the full text of the Separation and Distribution Agreement and the Newmark Holdings Limited Partnership Agreement, each as may be amended from time to time, which are filed as Exhibit 2 and Exhibit 5 hereto, respectively, and incorporated herein by reference.

Investment Agreement

On March 7, 2018, BGC, including through its subsidiary BGC U.S. OpCo, purchased 16,606,726 exchangeable limited partnership units of Newmark Holdings for approximately $242.0 million. The price per unit was based on the $14.57 closing price of Class A Common Stock on March 6, 2018 as reported on the NASDAQ Global Select Market. The exchangeable limited partnership units may be exchanged for shares of Class A Common Stock or Class B Common Stock. BGC and BGC U.S. OpCo funded the Investment using the proceeds of its Controlled Equity Offering Class A common stock sales program pursuant to the 2017 Sales Agreement.

BGC made the Investment on March 7, 2018 pursuant to an Investment Agreement, dated as of March 6, 2018 (the “Investment Agreement”), by and among BGC, BGC Holdings, BGC U.S. OpCo, BGC Global OpCo, the Issuer, Newmark Holdings and Newmark OpCo.

The foregoing description of the Investment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Investment Agreement, which is filed as Exhibit 3 hereto and incorporated herein by reference.

Exchange Agreement

On December 13, 2017, in connection with the Separation, the Issuer, BGC and CFLP entered into an Exchange Agreement, dated as of December 13, 2017 (the “Exchange Agreement”), as may be amended from time to time, which provides BGC, CFLP, CFGM and any other Qualified Class B Holder (as defined therein) entitled to hold Class B Common Stock under the Issuer’s Amended and Restated Certificate of Incorporation with the right to exchange at any time and from time to time, on a one-to-one basis, shares of Class A Common Stock then owned or subsequently acquired by such persons for shares of Class B Common Stock, up to the number of shares of Class B Common Stock that are authorized but unissued under the Issuer’s certificate of incorporation. Prior to the Distribution, however, without the prior consent of BGC, CFLP, CFGM and any other Qualified Class B Holder may not exchange such shares of Class A Common Stock into shares of Class B Common Stock.

The foregoing description of the Exchange Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Exchange Agreement, which is filed as Exhibit 4 hereto and incorporated herein by reference.
