puraDYN Filter Technologies Incorporated (AMEX:PFT) announced today that the Company has submitted to the American Stock Exchange notice of its intent to withdraw from listing its common stock, and has filed an application for delisting with the Securities and Exchange Commission (SEC) pursuant to Section 12(d) of the Securities Exchange Act of 1934. puraDYN's Board of Directors considered several factors in making this decision, including: -- Determination that the Company, as previously notified on April 28, 2005, would not be able to timely comply with the Exchange's ongoing financial compliance listing standards under Section 1003(a)(i) and (ii) of the Exchange's Company Guide. -- Subsequent notice received from the Exchange on June 24, 2005 that the Company is not in compliance with Sections 301, 711 and 713(a)(ii) of the Company Guide, the consequences of which would require the Company to either 1) limit the amount of financing of its previously announced private offering or 2) incur additional costs and defer receipt of the financing pending stockholder approval as required by the Exchange's rules. -- The expense of maintaining the listing of the Company's common stock on the Exchange, including the cost for Exchange-listed shares of complying with requirements relative to the Sarbanes-Oxley Act of 2002, which has had, and is expected to have, a significant negative effect on the Company's cash flow and earnings. -- Continued compliance with the listing rules and requirements of the Exchange and Sarbanes-Oxley demand significant attention and time from Company management and personnel that could be dedicated to developing business and pursuing strategic opportunities. Joseph V. Vittoria, Chairman, said, "After careful deliberation, our Board of Directors concluded that the needs of the Company and its stockholders are better served at this time and the foreseeable future by delisting puraDYN from the Exchange and trading its common stock on the OTC Bulletin Board. "In conjunction with senior management, we believe that this action will result in material savings to the Company and allow our team to focus solely on our business operations." puraDYN continues to be required to file reports with the SEC under Section 13 of the Securities Exchange Act of 1934, including quarterly and annual reports, and its common stock is expected in the ordinary course to be included for quotation on the OTC Bulletin Board. The Company will also continue to engage the services of its independent registered public accounting firm, Daszkal Bolton LLP, to perform quarterly and annual audits of the Company's financial statements and maintain many of the corporate governance improvements the Company achieved during its tenure on the Exchange. puraDYN will announce the new trading symbol and effective date of trading when received.
