Summa Reports 3^rd Quarter Earnings

Summa Industries (Nasdaq NM:SUMX) reports net income of $508,000, or $.13 per share, on sales of $31,541,000 for the three months ended May 31, 2005, versus net income of $1,390,000, or $.30 per share, on sales of $33,160,000 for the three months ended May 31, 2004.

	Three months ended
	May 31, 2005		May 31, 2004
Sales	$	31,541,000	$	33,160,000
Net income	$	508,000	$	1,390,000
Diluted earnings per share	$	.13	$	.30

Sales and earnings were adversely impacted primarily by weakness in the Optical Components Segment, which resulted from softness in demand for high-bay, high intensity discharge lighting products and other issues. Additionally, earnings have been substantially impacted by facility relocation costs. The effects of the relocation expenses and the pro forma earnings, calculated as though the relocation expenses had not been incurred, are as follows:
