Impinj Raises $22M to Accelerate RFID Product Development

Market Wire, July, 2004

Impinj, Inc., a fabless semiconductor company developing Radio Frequency Identification (RFID) solutions for supply chain and logistics automation, today announced that Mobius Venture Capital, Unilever Technology Ventures and the UPS Strategic Enterprise Fund have joined the company's previous investors, ARCH Venture Partners, Madrona Venture Group and Polaris Venture Partners, to provide $22 million in third-round funding. Impinj also announced that Aaron Cheatham, a Principal at Mobius Venture Capital, which led the financing round, has joined Impinj's board of directors.

"This new injection of capital from valued advisers puts Impinj on the fast track to delivering the semiconductor-based solutions that our customers in the rapidly emerging, multi-billion-dollar RFID market are demanding," said Dr. William Colleran, President and CEO of Impinj. "We will continue to drive quickly toward volume production of our first-generation RFID products while developing new products that conform to the emerging Generation 2 standard."

Impinj was founded in May 2000 by legendary semiconductor expert Dr. Carver Mead and Dr. Chris Diorio, co-chair of the EPCglobal, Inc. Hardware Action Group that is responsible for establishing worldwide RFID standards. Impinj's RFID products, including the Zuma RFID tags introduced earlier this year, address the mandates set forth by the world's largest retailers for low cost, long range, field-rewritable RFID systems that comply with EPCglobal standards. Impinj's advantages derive from its patented Self-Adaptive Silicon®, an integrated circuit design technology that enables high performance analog functions and nonvolatile memory, critical elements of RFID products.

"RFID technology is revolutionizing the retail supply chain," said Simon Ellis, Supply Chain Futurist at Unilever. "Impinj's solutions and expertise are key to ensuring that the consumer packaged goods industry is able to meet mandated worldwide RFID roll-out deadlines over the next 18 months."

"UPS believes RFID technology has the potential to enhance the management of global supply chains, particularly in the area of inventory management," said Alan Koenning, Fund Manager at UPS Strategic Enterprise Fund. "An investment in Impinj provides UPS with an opportunity to better understand new RFID solutions and gain insight into the use, acceptance, and performance of next generation chips."

Impinj will use the proceeds of this financing to move into volume production of its RFID products and to expand operations both at its Seattle headquarters and at its Orange County, California facility opened this January.

About Impinj, Inc.

Impinj, Inc. is a fabless semiconductor company whose patented Self-Adaptive Silicon® technology enables its two synergistic business lines: high performance RFID products and cost-effective semiconductor intellectual property (SIP). Impinj's semiconductor chips power high performance, enhanced-functionality RFID systems that fulfill the global mandates promulgated by the consumer packaged goods and retailing industries. The company is a leading contributor to the emerging RFID standards for high volume supply-chain applications worldwide and in April 2004, introduced Zuma(TM), the world's first RFID tag with long range, field rewritability. Impinj's innovative SIP products, core to the company's RFID tags, are licensed to leading semiconductor companies worldwide allowing them to cost-effectively integrate crucial nonvolatile memory (NVM) alongside analog and digital functionality on a single chip. Impinj's SIP products include the popular AEON(TM) memory, the world's first rewritable NVM technology compatible with logic CMOS manufacturing. Founded in May 2000 by semiconductor industry veterans Dr. Carver Mead and Dr. Chris Diorio, Impinj has raised over $50 million to date from venture capital firms ARCH Venture Partners, Madrona Venture Group, Mobius Venture Capital and Polaris Venture Partners and from strategic investors UPS Strategic Enterprise Fund and Unilever Technology Ventures.
