The Schedule 13D relates to the Class A Common Stock, par value $0.01 per share (the "Common Stock"), of SunCom Wireless Holdings, Inc. (the "Issuer"). On May 4, 2005, the Issuer changed its corporate name from Triton PCS Holdings, Inc. to SunCom Wireless Holdings, Inc. The Issuer's principal offices are located at 1100 Cassatt Road, Berwyn, Pennsylvania 19312. Except as modified herein, the Schedule 13D is unmodified. - 2 - Item 2. Identity and Background. (a) Michael E. Kalogris (b) Business address: c/o SunCom Wireless Management Company, Inc. 1100 Cassatt Road Berwyn, Pennsylvania 19312 (c) Mr. Kalogris is presently the Chairman of the Board of Directors and the Chief Executive Officer of SunCom Wireless Holdings, Inc. located at 1100 Cassatt Road, Berwyn, Pennsylvania 19312. (d) Mr. Kalogris has not, during the last five years, been convicted of a criminal proceeding (excluding traffic violations or similar misdemeanors). (e) Mr. Kalogris has not, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding been subjected to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws upon the finding of any violation with respect to such laws. (f) Mr. Kalogris is a citizen of the United States of America. Item 3. Source and Amount of Funds or Other Consideration. Mr. Kalogris acquired his shares of Common Stock through a combination of: (i) purchases of shares in connection with the founding, formation and initial funding of the Issuer and its subsidiaries; (ii) limited open market purchases following the Issuer's initial public offering; (iii) the Issuer's Employee Stock Purchase Plan; and (iv) awards of restricted stock. Mr. Kalogris used personal funds to purchase the shares of Common Stock described in clauses (i), (ii) and (iii). Item 4. Purpose of Transaction. Mr. Kalogris has no present plans or proposals that relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. However, Mr. Kalogris reserves the right to propose or participate in future transactions which may result in one or more of such actions, including but not limited to, an extraordinary corporate transaction such as a merger, reorganization or liquidation, sale of a material amount of assets of the Issuer or its subsidiaries, or other transactions which might have the effect of causing the Issuer's Common Stock to cease to be listed on a national securities exchange or causing the Common Stock to become eligible for termination of registration, under Section 12(g) of the Exchange Act. Item 5. Interest in Securities of the Issuer. The aggregate number of shares of the Issuer's Common Stock beneficially owned by Mr. Kalogris is 3,459,339, which represents 5.6% of the issued and outstanding shares of the Issuer's Common Stock as of April 29, 2005. Mr. Kalogris has the power to vote 3,459,339 shares of the Issuer's Common Stock and the power to dispose of 3,396,162 shares of the Issuer's Common Stock. He may be deemed to share dispositive power with respect to 63,177 shares of the Issuer's Common Stock held in trust, but he disclaims - 3 - beneficial ownership of all such shares. More specifically, as trustee, Mr. Kalogris has sole voting power with respect to the shares held by the trust. However, disposition of shares from the trust is accomplished by the Issuer delivering a distribution schedule to Mr. Kalogris, in his capacity as trustee, setting forth the recipients of shares held by the trust and the number of shares to be distributed from the trust in respect of each recipient. Mr. Kalogris, as Chairman of the Board and Chief Executive Officer of the Issuer, may be deemed to share dispositive power to the extent of his participation in determining the trust's distribution schedule. On May 25, 2005, the Compensation Committee of the Issuer's Board of Directors approved an award of 227,500 shares of Common Stock to Mr. Kalogris under the Issuer's Amended and Restated Stock and Incentive Plan, which shares vest ratably over three years and are subject to forfeiture under an employment agreement. No person other than Mr. Kalogris has the right to receive or the power to direct the receipt of dividends from or the proceeds from the sale of Common Stock owned beneficially by Mr. Kalogris.
