Upon consummation of the Business Combination, Invesat’s then-existing common units in AST OpCo were reclassified and reissued by AST OpCo into new AST OpCo Common Units on a 1-to-14.50149869 basis and Invesat received an equivalent number of non-economic Class B Common Stock.

CUSIP No. 00217D100 13D Page 7 of 11 pages

As a result of the Business Combination, as of the Closing Date, Invesat holds 9,932,541 AST OpCo Common Units,¹ 9,932,541 shares of the Issuer’s Class B Common Stock and 319,033 vested incentive equity options of AST OpCo (the “AST Incentive Equity Options”), which are subject to the terms of the AST 2019 Equity Incentive Plan and the applicable award agreement evidencing such AST Incentive Equity Options and the terms and conditions of the A&R Operating Agreement. The AST Incentive Equity Options are exercisable for “Incentive Equity Units” of AST OpCo, each of which is then redeemable for one share of Class A Common Stock on or after April 6, 2023, subject to the Issuer’s discretion (in its capacity as the managing member of AST OpCo) to allow Invesat LLC to exchange such securities for AST OpCo Common Units at an earlier time. The Issuer has agreed, in its capacity as the managing member of AST OpCo, to allow Invesat to exchange its AST Incentive Equity Options for AST OpCo Common Units following April 6, 2022.

Ms. Cisneros holds 326,211 vested AST Incentive Equity Options. Each vested AST Incentive Equity Option is redeemable for one “Incentive Equity Unit” of AST OpCo, which is further redeemable for one share of Class A Common Stock, on April 6, 2023, subject to the Issuer’s discretion (in its capacity as the managing member of AST OpCo) to allow Ms. Cisneros to exchange such securities for AST OpCo Common Units at an earlier time.

The unvested AST Incentive Equity Options vest and become exercisable with respect to 20% of the underlying Incentive Equity Units of AST OpCo on November 5, 2019 and the remaining portion will vest and become exercisable in 48 equal monthly installments thereafter. Each AST Incentive Equity Option will continue to be subject to the terms of the AST Incentive Plan and the applicable award agreement evidencing such AST Incentive Equity Option, and will further be subject in all respects to the terms and conditions of the A&R Operating Agreement.

The A&R Operating Agreement and Amended and Restated Certificate of Incorporation of the Issuer prohibit transfers of AST OpCo Common Units and shares of Class B Common Stock, subject to certain exceptions. From and after April 6, 2022, the Reporting Persons may redeem or exchange one common unit of AST OpCo for one share of Class A Common Stock or, at the election of the Issuer (in its capacity as the managing member of AST OpCo), a cash payment based on the value of Class A Common Stock. At the time of any such redemption or exchange, the Reporting Persons would forfeit an equivalent number of shares of Class B Common Stock to the Issuer (provided that the amount of any cash settlement is limited to the net proceeds from any issuance of shares of Class A Common Stock for the purpose of satisfying such settlement).

The foregoing description of the A&R Operating Agreement does not purport to be complete and is subject to and qualified in its entirety by the full text of the A&R Operating Agreement, a copy of which is included as Exhibit 99.4 to this Schedule 13D and is incorporated herein by reference.

Stockholders’ Agreement

In connection with the closing of the Business Combination, the Issuer and the Stockholder Parties entered into a stockholders’ agreement (the “Stockholders’ Agreement”).

As of the Closing Date, the Board initially consisted of 13 directors, with two director seats being vacant, which Abel Avellan may fill at any time. The Stockholder Parties have the right to nominate directors as follows: (i) Abel Avellan has the right to nominate seven members to the Board, including the two initial vacancies which Abel Avellan has the right to fill, (ii) Invesat, Vodafone, NPA Sponsor and American Tower each have the right to nominate one member to the Board, and (iii) Rakuten has the right to nominate two members to the Board.

Moreover, each of the Stockholder Parties agreed until the Sunset Date (as defined therein) (i) to take all necessary action reasonably available within their power, including casting all votes to which such Stockholder Party is entitled in respect of its Voting Shares (as defined therein), whether at any annual or special meeting, by written consent or otherwise, so as to vote its Voting Shares on all matters submitted to the stockholders of the Issuer in accordance with the recommendation of the Board and (ii) not to grant, or enter into a binding agreement with respect to, any proxy to any person in respect of such party’s equity securities of the Issuer that would prohibit such party from casting such votes in accordance with the foregoing provision.  Additionally, the Stockholders’ Agreement prohibits Invesat and the other Stockholder Parties from transferring AST OpCo Common Units received in connection with the Business Combination on the Closing Date prior to April 6, 2022, subject to certain exceptions.

Invesat and its permitted transferees will no longer be entitled to nominate a director to the Board if they (i) collectively, at any point after the Closing Date, do not hold at least five percent of the outstanding Class A Common Stock (assuming the exchange of all AST OpCo Common Units for shares of Class A Common Stock), (ii) become a Competitor (as defined in the Stockholders’ Agreement, a “Competitor”) of the Issuer, (iii) initiate a legal proceeding against the Issuer or a member of the Board or (iv) obtain the right to appoint a member or observer to the board (or similar governing body) of any Competitor of the Issuer.

The foregoing description of the Stockholders’ Agreement does not purport to be complete and is subject to and qualified in its entirety by the full text of the Stockholders’ Agreement, a copy of which is included as Exhibit 99.3 to this Schedule 13D and is incorporated herein by reference.
