Item 4. Purpose of Transaction

Reporting Persons or their affiliates may purchase additional securities or dispose of securities in varying amounts and at varying times depending upon Reporting Persons’ continuing assessments of pertinent factors, including the availability of shares of Common Stock or other securities for purchase at particular price levels, the business prospects of the Issuer, other business investment opportunities, economic conditions, stock market conditions, money market conditions, the attitudes and actions of the board of directors and management of the Issuer, the availability and nature of opportunities to dispose of shares of the Issuer and other plans and requirements of the particular entities. The Reporting Persons may discuss items of mutual interest with the Issuer, which could include items in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

CUSIP NO. 65345N 106

SCHEDULE 13D

Depending upon their assessments of the above factors, the Reporting Persons or their affiliates may change their present intentions as stated above and they may assess whether to acquire additional securities of the Issuer, including shares of Common Stock (by means of open market purchases, privately negotiated purchases, or otherwise) or to dispose of some or all of the securities of the Issuer under their control. The Reporting Persons or their affiliates may seek to acquire other securities of the Issuer, including other equity, debt, notes or other financial instruments related to the Issuer or the Common Stock (which may include rights or securities exercisable or convertible into securities of the Issuer), and/or sell or otherwise dispose of some or all of such Issuer securities or financial instruments (which may include distributing some or all of such securities to such Reporting Person’s respective partners, members or shareholder, as applicable) from time to time, in each case, in open market or private transactions, block sales or otherwise. Any transaction that any of the Reporting Persons or their affiliates may pursue may be made at any time and from time to time without prior notice and will depend on a variety of factors, including, without limitation, the price and availability of the Issuer’s securities or other financial instruments, the Reporting Persons’ or such affiliates’ trading and investment strategies, subsequent developments affecting the Issuer, the Issuer’s business and the Issuer’s prospects, other investment and business opportunities available to such Reporting Persons and their affiliates, general industry and economic conditions, the securities markets in general, tax considerations and other factors deemed relevant by such Reporting Persons and such affiliates.

The Reporting Persons intend to review their investment in the Issuer on an ongoing basis and, in the course of their review, may take actions (including through their affiliates) with respect to their investment or the Issuer, including communicating from time to time with the board of directors, members of management, other securityholders of the Issuer, or other third parties, advisors, such as legal, financial, regulatory, or other advisors, to assist in the review and evaluation of strategic alternatives. Such discussions and other actions may relate to various alternative courses of action, including, without limitation, those related to an extraordinary corporate transaction (including, but not limited to a merger, reorganization or liquidation) involving the Issuer or any of its subsidiaries; a sale or transfer of a material portion of the assets of the Issuer or any of its subsidiaries or the acquisition of material assets; the formation of joint ventures or other strategic alliances with the Issuer or any of its subsidiaries; changes in the present business, operations, strategy, future plans or prospects of the Issuer, financial or governance matters; changes to the board of directors or management of the Issuer; changes to the capitalization, ownership structure, dividend policy, business or corporate structure or governance documents of the Issuer; de-listing or de-registration of the Issuer’s securities; or any action similar to the foregoing. Such discussions and actions may be exploratory in nature, and not rise to the level of a plan or proposal.

James B. Fleming, the sole manager of CCIV, serves as a member of the board of directors of the Issuer and, in such capacity, may have influence over the corporate activities of the Issuer, including activities which may relate to items described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

SCHEDULE 13D

On October 28, 2021, the Issuer and Spartacus announced the completion of the previously announced transactions contemplated by the Merger Agreement (the “Transactions”).
