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

On December 13, 2012, Motricity, Inc. (the “Company”) received a letter (the “Delisting Notice”) from the NASDAQ Stock Market LLC (“NASDAQ”) notifying the Company that it has not regained compliance with Listing Rule 5450(a)(1), the continued listing requirement to maintain the closing bid price of its common stock at $1.00 per share, (the “Minimum Bid Requirement”) and, accordingly, that its common stock will be delisted from the NASDAQ Global Select Market. The Delisting Notice states that unless the Company requests an appeal of the determination to delist the Company, trading of the Company’s common stock will be suspended at the opening of business on December 24, 2012, and a Form 25-NSE will be filed with the Securities and Exchange Commission (the "SEC"), which will remove the Company’s common stock from listing on NASDAQ. If the Company files a request to appeal before 4:00 pm Eastern Time on December 20, 2012, delisting action will be stayed while the appeal is pending.

The Company intends to request a hearing and present its plan for regaining compliance with the Minimum Bid Requirement. As part of the Company's plan to regain compliance, the Company has included in its preliminary proxy statement/prospectus on Form S-4 (Registration Number 333-185510) filed with the SEC on December 17, 2012 (the “Proxy Statement”), among other proposals, a proposal (the "Proposal") seeing stockholder approval of its Restated Certificate of Incorporation to effect a reverse stock split such that each ten shares of common stock issued and outstanding prior to the reverse stock split will be exchanged for one share of common stock after the reverse stock split. If the Proposal is approved by the stockholders, it will be implemented by the Company's board of directors if it determines that a reverse stock split is appropriate to regain compliance with the Minimum Bid Requirement. There can be no assurance that the Proposal will be approved by stockholders, that the Proposal, if approved, would be sufficient to permit the Company to regain compliance with the Minimum Bid Requirement or that NASDAQ will grant the Company’s request for continued listing.

Item 8.01. Other Information.

On December 17, 2012, in its proxy statement the Company announced it plans to seek stockholder approval at its annual meeting for a reorganization in which the Company would become a wholly owned subsidiary of Mobile Systems Corp., a newly formed Delaware corporation (the “Reorganization”). In the Reorganization, each outstanding share of common stock of Motricity would be exchanged for one share of common stock of Mobile Systems Corp., each outstanding share of preferred stock of Motricity would be exchanged for one share of preferred stock of Mobile Systems Corp., each outstanding warrant to purchase shares of common stock of Motricity would be exchanged for a warrant to purchase an equivalent number of shares of Mobile Systems Corp, and each option to purchase shares of common stock of Motricity would be assumed by Mobile Systems Corp. and become exercisable for an equivalent number of shares of Mobile Systems Corp. The consolidated assets and liabilities of Mobile Systems Corp. immediately after the merger would be the same as the consolidated assets and liabilities of Motricity immediately prior to the merger. The sole purpose of the Reorganization is to protect the long-term value to the Company of its substantial net operating loss carryforwards against limitations that could be imposed as a result of certain “ownership changes” as specified under the Internal Revenue Code, which will be accomplished by imposing certain restrictions on the transfer of the common stock of Mobile Systems Corp. Under Mobile Systems Corp.’s certificate of incorporation, its common stock is subject to limited transfer restrictions that are intended to protect against a potential ownership change for tax purposes. The transfer restrictions are described in detail in the Proxy Statement. That filing also includes the full text of the transfer restrictions, as they appear in the certificate of incorporation of Mobile Systems Corp.

The Company said it plans to submit the transaction to a vote of its stockholders as part of the upcoming annual meeting of Motricity stockholders. The date of the annual meeting is currently set for January 29, 2013, pending clearance by the SEC of the Proxy Statement, and the record date for determining the

stockholders entitled to receive notice of and to vote at the annual meeting is December 31, 2012. The Reorganization requires the approval of the holders of a majority of the Company’s outstanding shares of common stock and Series J preferred stock, voting together as a single class (with each share of common stock having one vote and each share of Series J preferred stock having 40 votes). There can be no assurance that the Reorganization will be approved.

Item 1.02. Termination of a Material Definitive Agreement.

On December 17, 2012, Motricity, Inc. (the “Company”) received notice from AT&T Mobility LLC (“AT&T”) that AT&T is terminating the Second Amended and Restated Wireless Service Agreement #0001429 dated July 22, 2005 between the Company and AT&T, as amended, and all services thereunder (the “Portal Agreement”) effective June 30, 2012 pursuant to its right to termination for convenience thereunder.

Under the Portal Agreement, the Company hosts AT&T’s MediaNet and ATT.net portals in exchange for a monthly fee based on the number of subscribers and certain other fixed fees.

In 2011 and the first nine months of 2012, the Portal Agreement accounted for 39% and 42%, respectively, of the Company’s revenue. This revenue contributed positively to the Company’s cash flow from operations during these periods.

The Master Service Agreement, dated as of October 1, 2010, between the Company and AT&T, pursuant to which the Company hosts AT&T’s AppCenter storefront (the “Master Service Agreement”), remains in effect. No material relationship exists between the Company or its affiliates and AT&T, except in connection with the Portal Agreement and the Master Service Agreement.
