Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. On December 14, 2006, SunCom Wireless Holdings, Inc. (the "Company") received written notice from the New York Stock Exchange (the "NYSE") that the NYSE intends to suspend the Company's common stock from trading prior to market open on Tuesday, December 19, 2006 as a result of the Company's failure to satisfy the NYSE's continued listing standards. The NYSE also notified the Company that it intends to apply to the Securities and Exchange Commission to delist the Company's common stock pending completion of applicable procedures, including any appeal by the Company of the NYSE's decision. As previously disclosed, the Company had received notification from the NYSE on September 27, 2006, that the Company was not in compliance with the NYSE's continued listing standards for average market capitalization because SunCom's average market capitalization was less than $100 million over a consecutive 30 trading-day period. The Company had previously submitted a business plan to address non-compliance with the NYSE's continuing listing standards. After reviewing these materials, the NYSE decided to proceed with suspension of trading. In accordance with NYSE rules, the Company intends to appeal the NYSE's decision to pursue the delisting of the Company's common stock by requesting a review of the decision by a committee of the board of directors of the NYSE.
