        The only MetroPCS stockholder approvals required by the Business Combination Agreement are the Stock Issuance Proposal and each New Certificate of Incorporation Proposal. The Change in Control Payments Proposal is non-binding and advisory and the vote on such proposal will have no impact on whether the Proposed T-Mobile Transaction is completed. The Business Combination Agreement provides that the requisite MetroPCS stockholder approval of the Stock Issuance Proposal and each New Certificate of Incorporation Proposal is a condition to closing the Proposed T-Mobile Transaction.

        We urge you to vote "AGAINST" the Proposed T-Mobile Transaction by voting "AGAINST" each of the MetroPCS Special Meeting Proposals.

        The Board of Directors of MetroPCS has established the close of business on January 31, 2013 as the record date (the "Record Date") for determining those stockholders who will be entitled to notice of, and to vote at, the Special Meeting.

        This Proxy Statement and the enclosed WHITE proxy card are first being sent or given to stockholders of MetroPCS on or about March 1, 2013.

        This solicitation is being made by the PSAM Group and not by or on behalf of the Board of Directors of MetroPCS.

        A proxy may be given by any person who held shares of MetroPCS Common Stock on the Record Date. Whether or not you plan to attend the Special Meeting, you are urged to sign and date the enclosed WHITE proxy card and return it in the postage-paid envelope provided. Your latest-dated proxy is the only one that counts, so you may return the WHITE proxy card even if you have already delivered any other proxy. Please do not return any yellow proxy card sent to you by MetroPCS. If you have already returned a yellow proxy card sent to you by MetroPCS, that card will be automatically revoked if you complete and return the enclosed WHITE proxy card.

BACKGROUND OF THIS SOLICITATION

        On October 3, 2012, MetroPCS and Deutsche Telekom issued a joint press release announcing the execution and delivery of the Business Combination Agreement.

        On January 30, 2013, PSAM sent a letter (the "January 30, 2013 Letter") to the Board of Directors of MetroPCS and the Supervisory Board at Deutsche Telekom outlining certain issues related to the structure of the Proposed T-Mobile Transaction.

        On February 7, 2013, PSAM issued a press release announcing that it had sent the January 30, 2013 Letter to the Board of Directors of MetroPCS and the Supervisory Board at Deutsche Telekom.

        On February 7, 2013 MetroPCS issued a public response to the January 30, 2013 Letter stating that: "The [Board of Directors of MetroPCS] believes that the proposed combination with T-Mobile is in the best interests of MetroPCS and all MetroPCS stockholders and continues to recommend that MetroPCS stockholders vote in favor of the proposed combination."

        On February 13, 2013, PSAM issued a press release announcing, among other things, that PSAM planned to begin discussing its detailed analysis and views on the Proposed T-Mobile Transaction directly with MetroPCS stockholders in order to explain its reasons for believing that the Proposed T-Mobile Transaction on the then-currently proposed terms was not in the best interests of MetroPCS stockholders.

REASONS FOR THIS SOLICITATION

        The PSAM Group is soliciting proxies from holders of shares of MetroPCS Common Stock in opposition to the Proposed T-Mobile Transaction and specifically "AGAINST" each of the MetroPCS Special Meeting Proposals.

        The PSAM Group believes that the MetroPCS Special Meeting Proposals are a group of related proposals whose purpose is to facilitate, or which are conditioned upon the completion of, the Proposed T-Mobile Transaction, which the PSAM Group opposes in its present form. The Business Combination Agreement provides that the requisite MetroPCS stockholder approval of the Stock Issuance Proposal and each New Certificate of Incorporation Proposal is a condition to closing the Proposed T-Mobile Transaction, and the PSAM Group is soliciting proxies to vote against these proposals because it is opposed to the completion of the Proposed T-Mobile Transaction. While the Change in Control Payments Proposal is non-binding and advisory, and need not be approved for the Proposed Transaction to be completed, the PSAM Group believes that the purpose of the proposal is to demonstrate stockholder support for compensation that would be paid to MetroPCS management in connection with the Proposed T-Mobile Transaction, and therefore this proposal should not be approved if stockholders oppose the Proposed T-Mobile Transaction. The PSAM Group opposes the Adjournment Proposal because the PSAM Group believes that MetroPCS should not have additional time to solicit proxies to vote for the Stock Issuance Proposal and the New Certificate of Incorporation Proposals if it is unable to obtain the necessary votes by the date of the Special Meeting, which will be scheduled by MetroPCS.

        The PSAM Group is of the opinion that it would be better for MetroPCS to remain a stand-alone company, while examining opportunities to consummate alternative transactions, rather than accept the package of cash and securities being offered to MetroPCS stockholders in the Proposed T-Mobile Transaction. This opinion is based upon the following factors:

1.

The PSAM Group's concern about the capitalization of MetroPCS after the completion of the Proposed T-Mobile Transaction (MetroPCS after the completion of the Proposed T-Mobile Transaction is referred to herein as the "Combined Company"): The PSAM Group believes that the Combined Company will be more highly leveraged than either MetroPCS or T-Mobile is today, and that this degree of leverage is excessive and will lead to a credit rating for the Combined Company that will be substantially below investment grade.

2.

The PSAM Group's concern about the interest rate on the financing to be provided by Deutsche Telekom to the Combined Company: The PSAM Group believes that the interest rate on the inter-company debt that the Combined Company will owe to Deutsche Telekom will be substantially higher than the interest rates now being paid by PCS and T-Mobile, including the interest rate being paid by T-Mobile on its inter-company debt to Deutsche Telekom, and that this higher interest rate is excessive and will depress the value of the Combined Company's equity.



3.

The PSAM Group's concern about the proposed equity split between MetroPCS stockholders and optionholders, on the one hand, and Holding (or its designee), on the other hand, in the Combined Company under the Business Combination Agreement: The PSAM Group believes that based on MetroPCS's estimate of 2013 EBITDA (earnings before interest, taxes, depreciation and amortization) for the two companies, T-Mobile is being valued at a higher ratio to EBITDA than is MetroPCS, and in the opinion of the PSAM Group the higher relative valuation of T-Mobile is not justified by the relative growth rates or other factors affecting the value of the two companies' businesses.

        Given the factors described above, the PSAM Group believes that MetroPCS stockholders would be better off if each of the MetroPCS Special Meeting Proposals were voted down and MetroPCS continued as an independent company than if the Proposed T-Mobile Transaction were completed in its present form. The PSAM Group believes that the Proposed T-Mobile Transaction is likely to produce less value for MetroPCS stockholders than MetroPCS could produce as an independent company if it sold its existing spectrum assets and became a mobile virtual network operator (leasing capacity from another network operator) or purchased additional spectrum and continued as a mobile network operator. Alternatively, the PSAM Group believes that the defects in the Proposed T-Mobile Transaction could be remedied by an appropriate combination of reduction in the amount of inter-company debt between Deutsche Telekom and the Combined Company, reduction in the interest rate on such inter-company debt, and an increase in the percentage of the equity in the Combined Company retained by MetroPCS stockholders. The PSAM Group would be prepared to support the Proposed T-Mobile Transaction if the parties to the Proposed T-Mobile Transaction took these steps.

        Use your WHITE proxy card to vote "AGAINST" the Proposed T-Mobile Transaction by voting "AGAINST" each of the MetroPCS Special Meeting Proposals.

CERTAIN INFORMATION REGARDING THE PROPOSED T-MOBILE TRANSACTION

        According to the MetroPCS Proxy Statement, if the Proposed T-Mobile Transaction is consummated, MetroPCS would:

(i)

effect a recapitalization that includes a reverse stock split (the "Reverse Stock Split") of the MetroPCS Common Stock, pursuant to which each share of MetroPCS Common Stock outstanding as of the effective time of the reverse stock split (the "Effective Time") would represent thereafter one-half of a share of MetroPCS Common Stock;



(ii)

as part of the recapitalization, make a payment in cash (the "Cash Payment") in an amount equal to $1.5 billion (or approximately $4.06 per share pre-Reverse Stock Split), without interest, in the aggregate to the record holders of MetroPCS Common Stock immediately following the Effective Time; and



(iii)

immediately following the Cash Payment, issue and deliver to Holding or its designee shares of MetroPCS Common Stock equal to 74% of the fully-diluted shares of MetroPCS Common Stock outstanding immediately following the Cash Payment (with the percentage ownership of fully-diluted shares of MetroPCS Common Stock as of such time of Holding or its designee and the MetroPCS stockholders and optionholders being calculated as described in the

2

---

Table of Contents

Business Combination Agreement and the MetroPCS Proxy Statement) and Holding would deliver to MetroPCS all of the shares of capital stock of T-Mobile.

        According to the MetroPCS Proxy Statement, if the Proposed T-Mobile Transaction is consummated, MetroPCS stockholders would be entitled to receive the following: (i) the record holders of MetroPCS Common Stock immediately following the Effective Time would receive a one-time aggregate cash payment of $1.5 billion, or approximately $4.06 per share pre-Reverse Stock Split, as part of the recapitalization of MetroPCS and (ii) upon completion of the Proposed T-Mobile Transaction, MetroPCS stockholders and optionholders immediately prior to the completion of the Proposed T-Mobile Transaction collectively would own 26% of the Combined Company on a fully-diluted basis.

        The foregoing description is not complete and is qualified in its entirety by reference to the full text of the Business Combination Agreement, a copy of which is included as Annex A to the MetroPCS Proxy Statement. The Proposed T-Mobile Transaction and each of the MetroPCS Special Meeting Proposals are described in further detail in the MetroPCS Proxy Statement which is available at http://www.sec.gov.

CERTAIN INFORMATION REGARDING PARTICIPANTS IN THIS SOLICITATION OF PROXIES

        PSAM, PSAM GP and Mr. Schoenfeld are participants in this solicitation of proxies for the Special Meeting. Certain other individuals identified in Annex A to this Proxy Statement may also be deemed to be participants in such solicitation. Information concerning PSAM, PSAM GP and Mr. Schoenfeld and other persons who may be deemed to be participants in this solicitation of proxies for the Special Meeting is set forth in Annex A to this Proxy Statement and is incorporated into this Proxy Statement by reference.

OTHER PROPOSALS

        Other than as set forth above, the PSAM Group is not currently aware of any other proposals to be brought before the Special Meeting. Should other proposals be brought before the Special Meeting, the persons named on the WHITE proxy card will vote on such proposals in their discretion (provided, however, that such persons named on the WHITE proxy card will be permitted to use such discretionary authority only for matters which they do not know, a reasonable time before the solicitation, are to be presented at the Special Meeting).

VOTING PROCEDURES

        To vote "AGAINST" the Proposed T-Mobile Transaction at the Special Meeting, please sign and date the enclosed WHITE proxy card and return it to Innisfree M&A Incorporated in the enclosed postage-paid envelope. Submitting a proxy will not affect your right to attend the Special Meeting and vote in person.

How do I vote in person if I am a record holder?

        MetroPCS has indicated that only stockholders with an admission ticket will be admitted to the Special Meeting. If you are a record holder of MetroPCS Common Stock, an admission ticket is attached to the yellow proxy card provided by MetroPCS. However, if you hold your shares of MetroPCS Common Stock through a bank, broker, custodian or other record holder, you should ask the bank, broker, custodian or other record holder that holds your shares to provide you with a legal proxy, a copy of your account statement, or a letter from the record holder confirming that you beneficially own or hold shares of MetroPCS Common Stock as of the close of business on the Record Date. You also can obtain an admission ticket to the Special Meeting by presenting the legal proxy provided by MetroPCS, or confirming documentation of your account from your bank, broker,

custodian or other record holder, at the Special Meeting. All stockholders will be required to show a valid, government-issued, picture identification that matches the name on the admission ticket or the yellow proxy card provided by MetroPCS or confirming documentation from your bank, broker, custodian or other record holder before being admitted to the Special Meeting.

How do I vote by proxy if I am a record holder?

        To vote by proxy, you should complete, sign and date the enclosed WHITE proxy card and return it promptly in the enclosed postage-paid envelope. To be able to vote your shares in accordance with your instructions at the Special Meeting, we must receive your proxy as soon as possible but in any event prior to the Special Meeting. You may vote your shares without submitting a proxy to us if you vote in person or submit a proxy to MetroPCS.

What if I am not the record holder of my shares?

        If you hold your shares through a bank, broker, custodian or other record holder (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, broker, custodian or other record holder. Banks, brokers, custodians or other record holders who hold shares of MetroPCS Common Stock on behalf of their customers may not give a proxy to vote those shares without specific instructions from their customers. MetroPCS stockholders that hold shares through a bank, broker, custodian or other record holder who wish to vote in person at the special meeting will need to obtain a "legal proxy" from their bank, broker, custodian or other record holder.

What should I do if I receive a yellow proxy card from MetroPCS?

        If you submit a proxy to us by signing and returning the enclosed WHITE proxy card, do not sign or return any yellow proxy card or follow any voting instructions provided by MetroPCS unless you intend to change your vote, because only your latest-dated proxy will be counted.

        If you have already sent a yellow proxy card to MetroPCS and voted in favor of the MetroPCS Special Meeting Proposals, you may revoke it and vote against the MetroPCS Special Meeting Proposals simply by signing, dating and returning the enclosed WHITE proxy card.

What if I want to revoke my proxy or change my voting instructions?

        You may change or revoke your proxy at any time prior to the vote on the matters at the Special Meeting. If you are a record holder of MetroPCS Common Stock, you may revoke your proxy by (1) delivering a written revocation to (x) MetroPCS' Corporate Secretary, at its principal executive office, located at 2250 Lakeside Boulevard, Richardson, Texas 75082 or (y) Innisfree M&A Incorporated, at 501 Madison Avenue, 20th Floor, New York, NY 10022, (2) submitting another valid proxy card with a later date, including by signing, dating and returning the enclosed WHITE proxy card (3) voting by submitting a proxy by telephone or Internet prior to the date and time of the Special Meeting pursuant to the procedures established by MetroPCS and described in the MetroPCS Proxy Statement, or (4) attending the Special Meeting in person and giving MetroPCS' Inspector of Elections notice of your intent to vote your shares in person. If your shares are held in street name, you must contact the record holder of your MetroPCS Common Stock in order to revoke your proxy.

        If you choose to revoke a proxy by delivering a written revocation or a later-dated proxy to MetroPCS or by submitting new voting instructions to the record holder of your MetroPCS Common Stock, we would appreciate if you would assist us in representing the interests of stockholders on an informed basis by sending a copy of your revocation, proxy or new voting instructions to Innisfree M&A Incorporated, at 501 Madison Avenue, 20th Floor, New York, NY 10022 or by calling Innisfree

M&A Incorporated toll-free at (888) 750-5834 (banks and brokers may call collect at (212) 750-5833). Please remember, your latest-dated proxy is the only one that counts.

If I plan to attend the Special Meeting, should I still submit a proxy?

        Whether you plan to attend the Special Meeting or not, we urge you to submit the enclosed WHITE proxy card. Returning the enclosed WHITE proxy card will not affect your right to attend the Special Meeting and vote.

Who can vote?

        Only record holders of shares of MetroPCS Common Stock at the close of business on the Record Date are entitled to notice of, and to vote at, the Special Meeting. No other shares of MetroPCS capital stock are entitled to notice of and to vote at the Special Meeting. At the close of business on the Record Date, MetroPCS had outstanding and entitled to vote 367,887,191 shares of MetroPCS Common Stock, which includes 3,276,765 restricted shares beneficially owned by employees, officers and directors of MetroPCS subject to vesting.

        Even if you sell your shares of MetroPCS Common Stock after the Record Date, you will retain the right to execute a proxy in connection with the Special Meeting. It is important that you grant a proxy regarding shares you held on the Record Date, or vote those shares in person, even if you no longer own those shares.

How many votes do I have?

        Holders of MetroPCS Common Stock have one vote per share on each matter to be acted upon at the Special Meeting.

How will my shares be voted?

        If you give a proxy on the accompanying WHITE proxy card, your shares will be voted as you direct. If you submit a signed WHITE proxy card without instructions, your shares will be voted "AGAINST" each of the MetroPCS Special Meeting Proposals. Submitting a signed WHITE proxy card without instructions will also entitle the persons named on the WHITE proxy card to vote your shares in accordance with their discretion on matters not described in this Proxy Statement that properly come before the Special Meeting (provided, however, that such persons named on the WHITE proxy card will be permitted to use such discretionary authority only for matters which they do not know, a reasonable time before the solicitation, are to be presented at the Special Meeting).

        If MetroPCS stockholders holding shares of MetroPCS Common Stock in street name do not provide voting instructions, their shares will not be voted and will therefore be considered broker "non-votes."

        Unless a proxy specifies otherwise, it will be presumed to relate to all shares held of record on the Record Date by the person who submitted it.

What is required for a quorum at the Special Meeting?

        In order to conduct business at the Special Meeting, holders of a majority of the outstanding shares of MetroPCS Common Stock entitled to vote on the Record Date must be present in person or represented by proxy at the Special Meeting for there to be a quorum. In addition, according to the MetroPCS Proxy Statement, certain unvested shares of restricted MetroPCS Common Stock issued pursuant to MetroPCS equity incentive compensation plans will count towards a quorum because such shares will be voted by MetroPCS on the proposals to be considered at the Special Meeting in the same proportion as the rest of the shares of MetroPCS Common Stock that are voted. If you hold your

5

---

Table of Contents

shares through a bank, broker, custodian or other record holder, please refer to your proxy card, voting instruction form, or the information forwarded by your bank, broker, custodian or other record holder to determine how and when to vote your shares. Unless you direct your bank, broker, custodian or other record holder on how to vote by the time and date specified by them, they will be unable to vote your shares. All shares of MetroPCS Common Stock represented at the Special Meeting, including abstentions, will be treated as shares that are present and entitled to vote for purposes of determining the presence of a quorum.

What vote is required to approve each proposal?

        Stock Issuance Proposal:    Assuming the presence of a quorum, the affirmative vote of a majority of the votes cast (in person or by proxy) by holders of MetroPCS Common Stock at the Special Meeting is required to approve the Stock Issuance Proposal, provided that the holders of a majority of the MetroPCS Common Stock outstanding on the Record Date vote on the Stock Issuance Proposal. If you vote to abstain, it will have the same effect as voting against this proposal. If you fail to vote or fail to instruct your bank, broker, custodian or other record holder how to vote, it will have no effect on the voting outcome of this proposal, but it will make it more difficult to have a quorum or meet the requirement that the holders of a majority of the MetroPCS Common Stock outstanding on the Record Date vote on this proposal.

        New Certificate of Incorporation Proposal:    Assuming the presence of a quorum, the affirmative vote of a majority of the MetroPCS Common Stock outstanding on the Record Date is required to approve each New Certificate of Incorporation proposal. If you vote to abstain, or if you fail to vote or fail to instruct your bank, broker, custodian or other record holder how to vote, it will have the same effect as voting against these proposals.

        Change in Control Payments Proposal:    Assuming the presence of a quorum, the affirmative vote of a majority of the votes cast (in person or by proxy) by holders of MetroPCS Common Stock at the Special Meeting is required to approve, on a non-binding, advisory basis, the Change in Control Payments Proposal. While the MetroPCS board has stated that it intends to consider the vote resulting from the Change in Control Payments Proposal, the vote is advisory and therefore not binding on MetroPCS, the MetroPCS board or the compensation committee of the MetroPCS board. Accordingly, because MetroPCS is contractually obligated to pay the change in control payments, if the transaction is completed, the change in control payments will be payable, subject only to the conditions applicable to such payments, regardless of the outcome of the advisory, non-binding vote. If you vote to abstain, or if you fail to vote or fail to instruct your bank, broker, custodian or other record holder how to vote, it will have no effect on the voting outcome of this proposal.

Adjournment Proposal:

•

If a quorum is not present at the Special Meeting:



•

The affirmative vote of a majority of the shares of MetroPCS Common Stock present at the Special Meeting (in person or by proxy) and entitled to vote on this proposal is required to approve this proposal.



•

If you vote to abstain, it will have the same effect as voting against this proposal.



•

If you fail to vote or fail to instruct your bank, broker, custodian or other record holder how to vote, it will have no effect on the voting outcome of this proposal.



•

If a quorum is present at the Special Meeting:



•

The affirmative vote of a majority of the votes cast (in person or by proxy) by holders of MetroPCS Common Stock at the Special Meeting is required to approve this proposal.

If you vote to abstain, it will have no effect on the voting outcome of this proposal.

If you fail to vote or fail to instruct your bank, broker, custodian or other record holder how to vote, it will have no effect on the voting outcome of this proposal.

The only MetroPCS stockholder approvals required by the Business Combination Agreement are the Stock Issuance Proposal and each New Certificate of Incorporation Proposal. The Change in Control Payments Proposal is non-binding and advisory and the vote on such proposal will have no impact on whether the Proposed T-Mobile Transaction is completed. The Business Combination Agreement provides that the requisite MetroPCS stockholder approval of the Stock Issuance Proposal and each New Certificate of Incorporation Proposal is a condition to closing the Proposed T-Mobile Transaction.

How can I receive more information?

        If you have any questions about giving your proxy or about our solicitation, or if you require assistance, please call Innisfree M&A Incorporated, toll-free at (888) 750-5834 (banks and brokers may call collect at (212) 750-5833).

NO APPRAISAL RIGHTS

        Under applicable law, MetroPCS stockholders do not have the right to an appraisal of the value of their shares in connection with the Proposed T-Mobile Transaction.

SOLICITATION OF PROXIES

        Proxies will be solicited by mail, telephone, facsimile, telegraph, the internet, e-mail, newspapers and other publications of general distribution and in person. Directors, officers and certain employees of members of the PSAM Group may assist in the solicitation of proxies without any additional remuneration.

        The PSAM Group has retained Innisfree M&A Incorporated ("Innisfree") for solicitation and advisory services in connection with solicitations relating to the Special Meeting, for which Innisfree is to receive a retainer fee of $50,000, plus an additional fee to be mutually agreed upon by the PSAM Group and Innisfree in connection with the solicitation of proxies for the Special Meeting. Up to 50 people may be employed by Innisfree in connection with the solicitation of proxies for the Special Meeting. The PSAM Group has also agreed to reimburse Innisfree for out-of-pocket expenses and to indemnify Innisfree against certain liabilities and expenses, including reasonable legal fees and related charges. Innisfree will solicit proxies for the Special Meeting from individuals, brokers, banks, bank nominees and other institutional holders.
