SPX ANNOUNCES 2011 ANNUAL GUIDANCE

Estimates 5 to 10 Percent Revenue Growth in 2011

2011 Earnings From Continuing Operations Range of $4.20 to $4.50 Per Share

Targets EPS Increase of Approximately 24 Percent Over 2010* Adjusted EPS

CHARLOTTE, NC — January 19, 2011 — SPX Corporation (NYSE:SPW), today announced its 2011 annual financial guidance. “We are encouraged going into 2011 and believe we are now in the early stages of recovery. For 2011 we expect organic growth in all four of our segments. We are targeting an EPS increase of approximately 24 percent over 2010* adjusted EPS,” said SPX Chairman, President and Chief Executive Officer Christopher J. Kearney.

“Key macroeconomic drivers continue to indicate growing worldwide demand for power and energy, food and beverage, and vehicle service, especially in emerging markets such as India, Africa and China. We believe that SPX will continue to play a significant role in meeting these global demands and have stepped up our investment in innovation to help meet our customers’ business needs.

“We remain focused on maintaining strong liquidity and financial flexibility.  Based on better than anticipated operating cash flow, we were able to make a voluntary contribution of $100 million to our pension plans in 2010 and anticipate we will still deliver full year adjusted free cash flow** in line with our previously communicated range of $180 to $220 million,” Kearney added.

SPX stated that it expects the following results in 2011:

·                  Revenues are expected to be in the range of $5.2 to $5.4 billion, resulting in an increase of 5% to 10% compared to 2010. Organic revenues** are expected to increase 2% to 7% from 2010, while completed acquisitions and the impact of currency fluctuations are expected to increase reported revenues by approximately 3% from 2010.

·                  Earnings from continuing operations are expected to be $4.20 to $4.50 per share.

·                  Net cash from continuing operations is expected to be $370 to $410 million, while capital expenditures are expected to be approximately $150 million. The resulting free cash flow** range is expected to be between $220 and

$260 million. This performance represents 100% to 120% conversion of expected net income.
