On April 6, 2005, Spire Corporation (Nasdaq: SPIR) received a Nasdaq Staff Determination indicating that the Company is no longer in compliance with the $10,000,000 minimum stockholders' equity requirement for continued listing set forth in Nasdaq Marketplace Rule 4450(a)(3), and that its common stock is, therefore, subject to delisting from the Nasdaq National Market. Because the Company fails to satisfy Marketplace Rule 4450(a)(3), the Nasdaq Staff is reviewing the Company's eligibility for continued National Market listing and has requested that the Company provide, on or before April 13, 2005, the Company's plan to achieve and sustain compliance with Nasdaq listing standards. The Company intends to present such plan to the Nasdaq Staff. If, after conclusion of its review, Nasdaq determines that the Company has not presented a sufficient plan to achieve and sustain compliance, it will provide written notification that the Company's common stock will be delisted. If the Company were to receive such a written notification, it would likely appeal the decision to a Nasdaq Listing Qualifications Panel. The Company is currently evaluating its options with respect to its response to the notice. SECTION 9 - FINANCIAL STATEMENTS AND EXHIBITS ITEM 9.01 FINANCIAL STATEMENTS AND EXHIBITS. (c) Exhibits.
