LIVERMORE, CA — October 19, 2004 — FormFactor, Inc. (Nasdaq: FORM) today announced its financial results for the third quarter of fiscal year 2004, ended September 25, 2004. Quarterly revenues were $51.4 million, up 19% from $43.2 million in the second quarter of fiscal year 2004, and up 97% from $26.1 million for the third quarter of fiscal year 2003.

Operating income for the third quarter of fiscal year 2004 was 23.0% of revenues, compared to 25.3% for the second quarter of fiscal year 2004, and 11.9% for the third quarter of fiscal year 2003, primarily due to non-recurring startup cost related to our new manufacturing facility and the adoption of an employee profit sharing plan for non executive employees.

Net income for the third quarter of fiscal year 2004 was $7.5 million or $0.19 per share on a fully diluted basis, compared to $6.8 million or $0.17 per share on a fully diluted basis for the second quarter of fiscal year 2004, and $2.2 million or $0.06 per share on a fully diluted basis for the third quarter of fiscal year 2003.

Bookings of $45.1 million for the third quarter of fiscal year 2004 declined 12% from $51.2 million for the second quarter of fiscal year 2004 and were up 55.2% from $29.1 million for the third quarter of fiscal year 2003.

Igor Khandros, President and CEO of FormFactor stated, “During the third quarter we produced the incremental capacity ramp of $8.2 million in product shipped, the strongest experienced in the company’s history. This capacity ramp is allowing bookings to normalize and reflect our growing ability to turn more orders into revenue in a given quarter. The fundamentals in our key end markets remained intact with continued growth, diversity of new designs in all segments, and the ramp of 300mm production facilities at our customers. The next wave of tooling cycles is emerging in DRAM where we saw continued momentum in DDRII and sub 110 nanometer demand.”
