SPX to Acquire APV

Acquisition to Expand SPX Global Process Equipment Manufacturing and Distribution Operations

Charlotte, NC – October 31, 2007 – SPX Corporation (NYSE: SPW) today announced that it has entered into a definitive agreement to acquire APV, a global manufacturer of process equipment and engineered solutions primarily for the sanitary market. APV is a division of Invensys PLC, an international industrial automation, transportation and controls group headquartered in London. APV will become a part of SPX’s flow technology segment.

APV’s primary products include pumps, valves, heat exchangers and homogenizers for the food, dairy, beverage and pharmaceutical industries. SPX expects the transaction to close by year-end 2007, subject to customary regulatory approvals and closing conditions, including resolution of the purchase and sale of APV France.

“APV is a strong strategic fit with SPX and will expand our manufacturing, sales and distribution operations for process equipment in Europe, Asia Pacific and worldwide,” said Chris Kearney, Chairman, President and CEO of SPX. “By combining APV’s research and development and engineering expertise, together with its strong portfolio of process solutions and technical knowledge, with SPX’s existing businesses, we expect to enhance our growth in the flow technology arena,” he added.

SPX has agreed to pay 250 million British pounds (GBP) (approximately $510 million) for APV, subject to closing adjustments. Revenues for APV were about $800 million for the fiscal year ending March 31, 2007. SPX plans to fund the acquisition with a mixture of borrowings and cash on hand. APV has approximately 3,000 employees in over 40 countries. The addition of APV will bring the total number of SPX employees to approximately 17,000 worldwide.

“APV’s products are highly complementary to our existing flow product portfolio and we expect significant product, production and cost synergies for our process equipment business,” said Don Canterna, SPX Segment President, Flow Technology.

This is the third European acquisition by SPX in 2007. The company previously acquired the European diagnostics division of Johnson Controls, located in Pontoise, France, and Matra-Werke GmbH, a wholly owned subsidiary of KION Group GmbH, located in Wiesbaden Germany.

The company will discuss additional details of this acquisition during a previously scheduled investor webcast to report third quarter 2007 earnings on Wednesday, October 31, at 8:30 a.m. Eastern Time with Chris Kearney, Chairman, President and CEO, Patrick O’Leary, Executive Vice President and Chief Financial Officer and Don Canterna, SPX
