Item 2.02. Results of Operations and Financial Condition.

On May 2, 2007, SPX Corporation (the “Company”) issued the press release attached as Exhibit 99.1 hereto and incorporated herein by reference.

The press release incorporated by reference into this Item 2.02 contains disclosure regarding free cash flow from continuing operations. Free cash flow from continuing operations is defined, for purposes of this press release, as cash flow from continuing operations less capital expenditures from continuing operations. The Company’s management believes that free cash flow from continuing operations is a useful financial measure for investors in evaluating the cash flow performance of multi-industrial companies, since it provides insight into the cash flow available to fund such things as equity repurchases, dividends, mandatory and discretionary debt reduction and acquisitions or other strategic investments. In addition, although the use of free cash flow from continuing operations is limited by the fact that the measure can exclude certain cash items that are within management’s discretion, free cash flow from continuing operations is a factor used by the Company’s management in internal evaluations of the overall performance of its business. Free cash flow from continuing operations is not a measure of financial performance under accounting principles generally accepted in the United States (“GAAP”), should not be considered a substitute for cash flows from operating activities as determined in accordance with GAAP, should be used in combination with cash flows from operating activities as determined in accordance with GAAP, and may not be comparable to similarly titled measures reported by other companies.

The press release also contains disclosure regarding organic revenue growth (decline), which is defined, for purposes of this press release, as revenue growth (decline) excluding the effects of foreign currency fluctuations and acquisitions and divestitures. The Company’s management believes that this metric is a useful financial measure for investors in evaluating our operating performance for the periods presented because excluding the effect of currency fluctuations and acquisitions and divestitures, when read in conjunction with the Company’s revenues, presents a useful tool to evaluate the Company’s ongoing operations and provides investors with a tool they can use to evaluate the Company’s management of assets held from period to period. In addition, organic revenue growth (decline) is one of the factors the Company’s management uses in internal evaluations of the overall performance of its business. This metric, however, is not a measure of financial performance in accordance with GAAP and should not be considered a substitute for revenue growth (decline) as determined in accordance with GAAP and may not be comparable to similarly titled measures reported by other companies.

Refer to the tables included in the press release for the components of the Company’s free cash flow from continuing operations, and organic revenue growth and for the reconciliations to their respective comparable GAAP measures.

The information in this Report is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject

to the liabilities of that Section. The information in this Report shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.
