MILPITAS, California, October 30, 2007 — Nanometrics Incorporated (Nasdaq: NANO), a leading supplier of advanced metrology equipment to the semiconductor industry, today announced its financial results for the third quarter ended September 29, 2007.

Revenues for the third quarter were a record $38.6 million, an increase of 3.5% compared to second quarter 2007 revenues of $37.3 million and an increase of 33% over revenues of $29.1 million for the third quarter of 2006. Net income for the third quarter of 2007 was $2.0 million, or $0.11 per diluted share.

Going forward, we will continue to focus on profitability, cash flow and predictability, with the added objectives of improving competitiveness and customer satisfaction.”
