ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION. On May 11, 2005, the Registrant issued a press release revising the Registrant's financial results for the fiscal quarters ended December 31, 2004 and March 31, 2005. A copy of the Registrant's press release is attached hereto as Exhibit 99.1. ITEM 4.02 NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED AUDIT REPORT OR COMPLETED INTERIM REPORT. (a) On May 10, 2005, in connection with the preparation of the consolidated financial statements for the second quarter of fiscal 2005, the Registrant ascertained that in the first quarter of the year there was an inventory valuation error in determining the garage door segment's cost of goods sold. This inventory valuation error was caused by unprecedented increases in the segment's raw material costs and correction of this error was included in the press release which previously reported operating results for the second quarter of 2005. However, the Registrant has since determined to reflect the adjustment to correct cost of goods sold in the first quarter of 2005 by restating that period's operating results. The restatement will not change previously disclosed earnings, cash flows, or financial position for the six months ended March 31, 2005 and will result in an estimated $1,260,000 decrease to bring previously reported first quarter net income to $9,192,000 and a corresponding increase to bring second quarter net income to $4,144,000. First quarter diluted earnings per share will decrease $.05 to an estimated $.29 per share and second quarter diluted earnings per share will increase $.04 to an estimated $.13 per share. The Registrant's Chief Financial Officer and the Audit Committee of the Board of Directors discussed the matters disclosed in this filing with PricewaterhouseCoopers LLC, the Registrants independent registered public accounting firm. As a consequence of its decision to restate the first quarter financial statements the Registrant reconsidered its assessment of disclosure controls and procedures with a focus on the control deficiency (application of raw material purchase price variances) that did not sufficiently address the rising raw material costs. Reflecting the correction of the previously issued financial statements in the quarter ended March 31, 2005 would be material to that period, and therefore, the Registrant believes that a restatement of the prior period interim financial statements is appropriate. The impact of the inventory valuation error on the year and fourth quarter ended September 30, 2004 was not material, and therefore was included as part of the restatement adjustment made to cost of goods sold and inventory for the quarter ended December 31, 2004. However, the Registrant does not consider the effect of correcting the previously issued quarterly financial statements to be material to the interim period ended December 31, 2004 and thus has concluded that the control deficiency that gave rise to the inventory valuation error does not constitute a material weakness at December 31, 2004 or September 30, 2004. Additionally, the Registrant concluded that the error was not a material weakness at March 31, 2005 because additional control procedures, including the timely review of raw material purchase price variances, were implemented prior to March 31, 2005, which procedures are designed to provide reasonable assurance that such an error will not recur. Based on the above, the Registrant concludes that its disclosure controls and procedures were effective at March 31, 2005. 2

     Jericho,  New York,  May 11, 2005 - Griffon  Corporation  (NYSE:GFF)  today
announced that in connection with the preparation of the consolidated  financial
statements for the second quarter of fiscal 2005, the company  ascertained  that
in the first  quarter  of the year  there was an  inventory  valuation  error in
determining  the  garage  door  segment's  cost of goods  sold.  This  inventory

However,  the company has since  determined to reflect the adjustment to correct

operating  results.   The  restatement  will  not  change  previously  disclosed
earnings,  cash flows, or financial  position for the six months ended March 31,
2005 and will result in an  estimated  $1,260,000  decrease to bring  previously
reported first quarter net income to $9,192,000 and a corresponding  increase to
bring second quarter net income to $4,144,000.  First quarter  diluted  earnings

     The Company did not file its quarterly  report on Form 10-Q,  which was due
