3D Systems Receives Nasdaq Delisting Notice
ROCK HILL, South Carolina, April 5, 2007 - 3D Systems Corporation (NASDAQ: TDSC), a leading provider of Rapid 3-D Modeling, Prototyping and Manufacturing solutions, today announced that it has received a Staff Determination notice from The Nasdaq Stock Market stating that the company’s common stock is subject to delisting from The Nasdaq Stock Market. The notice was issued in accordance with standard Nasdaq procedures as a result of the previously announced delayed filing of the company’s Annual Report on Form 10-K for the year ended December 31, 2006. Timely filing of periodic reports is a requirement for continued listing under Nasdaq Marketplace Rule 4310(c)(14).
The Company previously received a similar Staff Determination notice from The Nasdaq Stock Market when it did not timely file its Form 10-Q for the quarterly period ended September 30, 2006. As previously disclosed, the Company received notice from Nasdaq of a determination to continue the listing of shares of the Company’s common stock on the Nasdaq Stock Market after the Company filed that Form 10-Q, which contained restated financial information, early in February.
As the company previously stated in a Form 12b-25 filed with the SEC on March 19, 2007, it was not able to undertake the work necessary to close its 2006 financial records or to begin preparing its Annual Report on Form 10-K for the year ended December 31, 2006 until the work necessary to file its third-quarter 2006 Form 10-Q was completed in early February. While the company has been diligently preparing its Annual Report on Form 10-K, it was nonetheless unable to meet the extended filing date of April 2, 2007 for its Annual Report on Form 10-K. The company currently anticipates that it will file its Annual Report on Form 10-K as promptly as practicable.
As permitted by the Nasdaq Marketplace Rules, the company intends to appeal the delisting of its common stock and therefore plans to timely request a hearing before a Nasdaq Listing Qualifications Panel, which will automatically stay any delisting of the company’s common stock pending the Panel’s review and determination.
“Our current inability to remain timely in our periodic filing requirements is a serious matter,” said Abe Reichental, 3D Systems’ President and Chief Executive Officer. “While it is Nasdaq’s customary practice to send notices such as this one to all Nasdaq-listed companies in similar circumstances, we plan to file our Form 10-K as promptly as practicable and are taking all remedial actions that are necessary to maintain our Nasdaq listing.”
