Item 2.01 Completion of Acquisition or Disposition of Assets.

On April 9, 2013, Motricity, Inc. (“Motricity”) and Voltari Corporation (“Voltari”) consummated a transaction intended to protect the long-term value of Motricity’s substantial net operating loss carryforwards. Pursuant to the Agreement and Plan of Reorganization by and between Motricity, Voltari and Voltari Merger Sub, Inc., dated as of February 8, 2013 (the “Agreement and Plan of Reorganization”), Motricity became a wholly owned subsidiary of Voltari, each outstanding share of common stock of Motricity (“Motricity Common Stock”) was converted into the right to receive one share of common stock of Voltari (“Voltari Common Stock”), each outstanding share of preferred stock of Motricity (“Motricity Preferred Stock”) became the right to receive one share of preferred stock of Voltari (“Voltari Preferred Stock”), each outstanding warrant to purchase shares of Motricity Common Stock became the right to receive a warrant to purchase an equivalent number of shares of Voltari Common Stock, and each option to purchase shares of Motricity Common Stock was assumed by Voltari and became exercisable for an equivalent number of shares of Voltari Common Stock (the “Reorganization”). Each share of Voltari Common Stock is subject to certain transfer restrictions (that were not applicable to Motricity) prohibiting transfers having the effect of increasing the ownership of Voltari Common Stock by (i) any person from less than 5% to 5% or more or (ii) any person owning or deemed to own 5% of more of Voltari’s Common Stock (the “Transfer Restrictions”).

The Agreement and Plan of Reorganization was approved and adopted by Motricity’s stockholders at Motricity’s special meeting of stockholders held on April 9, 2013 (the “Special Meeting”).

Upon completion of the Reorganization, Motricity became a wholly owned subsidiary of Voltari, which replaces Motricity as the publicly held corporation. As further described below, it is anticipated that, as of April 10, 2013, shares of Voltari Common Stock will commence trading on the NASDAQ Capital Market under the symbol “VLTC.”

The directors and executive officers of Voltari immediately following the Reorganization are the same individuals who were directors and executive officers of Motricity immediately prior to the Reorganization.

Upon completion of the Reorganization, Voltari Common Stock was deemed to be registered under Section 12(b) of the Securities Exchange Act of 1934, as amended, pursuant to Rule 12g-3(a) promulgated thereunder. For purposes of Rule 12g-3(a), Votlari is the successor issuer to Motricity.

The foregoing description of the Agreement and Plan of Reorganization and the Transfer Restrictions is qualified in its entirety by reference to the Agreement and Plan of Reorganization and the Amended and Restated Certificate of Incorporation of Voltari Corporation, which are attached hereto as Exhibits 2.1 and 3.1, respectively, and are incorporated herein by reference.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

In anticipation of the Reorganization, on March 22, 2013, Motricity notified the NASDAQ Stock Market (“NASDAQ”) that upon completion of the Reorganization each issued and outstanding share of Motricity Common Stock would become the right to receive one share of Voltari Common Stock, and Motricity requested that NASDAQ (i) suspend trading in Motricity Common Stock on the NASDAQ Capital Market under the symbol “MOTR” and (ii) commence trading of shares of Voltari Common Stock on the NASDAQ Capital Market under the symbol “VLTC” as of the open of business on Wednesday, April 10, 2013.
