GRIFFON CORPORATION ANNOUNCES RECORD OPERATING RESULTS FOR THE SECOND QUARTER OF FISCAL 2004

Jericho, New York, April 29, 2004 — Griffon Corporation (NYSE: GFF) reported record operating performance for the second quarter of fiscal 2004, ended March 31, 2004, with each of its operating units reflecting increases in sales, operating income and margins.

Net sales for the quarter were $317,636,000 compared to $277,330,000 for the second quarter of fiscal 2003. Income before income taxes increased to $19,348,000 from $11,236,000. Net income was $8,662,000 in the current quarter, up from $4,617,000 in the second quarter of 2003. Basic earnings per share for the quarter was $.29 compared to $.14 last year and diluted earnings per share was $.27 compared to $.14 in 2003.

Specialty plastic films reflected substantially higher sales and operating profit. The sales growth was due to an improved product mix, selling price adjustments to pass through raw material price increases to customers and the effect of a weaker U.S. dollar on translated foreign sales. Specialty plastic films’ operating profit benefited from the sales growth and increased operating efficiencies. The building products operations contributed to the quarter’s improved operating results with higher unit sales of garage doors in both the retail and dealer channels of distribution, sales gains in installation services and its elimination last year of an underperforming location and effective expense control. The electronic information and communication systems segment, Telephonics, had higher sales and operating profit due to the effect of recently awarded contracts and growth in defense production programs. Consolidated earnings in the quarter reflected increased interest expense of $1,100,000 associated with the company’s convertible subordinated notes which were sold in the latter part of fiscal 2003.

Net sales for the six months ended March 31, 2004 were $656,138,000 compared to $579,484,000 for the first six months of fiscal 2003. Income before income taxes for the six months rose to $45,006,000, up from $32,317,000 last year. Net income increased to $21,777,000 from $15,537,000 for the first six months of 2003. Diluted earnings per share for the first half was $.69 compared to $.46 last year.

Cash flow from operations during the quarter was $18,000,000 which was used to fund treasury stock purchases of $9,000,000 and capital expenditures of $10,000,000, principally for the specialty plastic films segment’s capital expansion programs.
