Press Release

LIVERMORE, CA–(Marketwired – May 19, 2016) – FormFactor, Inc. (NASDAQ: FORM) today announced that for the third consecutive year, it achieved the RANKED 1^st spot in the 2016 THE BEST Suppliers of Subsystems. Subsystems — which includes semiconductor probe cards — is one of 11 market segments covered in the annual Customer Satisfaction Survey produced by leading market research firm, VLSIresearch.

The RANKED 1^st Supplier achievement acknowledges FormFactor’s enduring commitment to customers. The company retained its customer satisfaction leadership position by commanding the highest scores in 12 of the 13 THE BEST Subsystems Supplier award categories, and tying in the last. FormFactor achieved its highest rated categories in “Partnering” and “Technology Leadership.”

“Being ranked THE BEST Supplier of Subsystems by our customers for three consecutive years is a testament to the technology expertise and dedication of the FormFactor team,” said CEO Mike Slessor. “We are very pleased that our continued commitment to industry-leading R&D and support investments, guided by close customer collaborations, is reflected in both this ranking and our increasing share in the advanced probe card market.”

The company was also recognized for business performance when it was named Top Supplier of Semiconductor Probe Cards Worldwide for 2015. That report, released last month by VLSIresearch, revealed that FormFactor’s growth for 2015 (by revenue) out-paced overall probe card market growth for the same period.

G. Dan Hutcheson, CEO of VLSIresearch, attributed FormFactor’s sustained superior rankings to the company’s ability to enable the quality and reliability its customers need to innovate next-generation devices. “This year’s result shows that FormFactor continues to deliver the technology, service and technical support that enable customers to meet aggressive market windows, while reducing their overall cost of test,” he said.
