Item 2.02.  Results of Operations and Financial Condition.

On November 2, 2011, 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 as operating 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”), and 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 as revenue growth (decline) excluding the effects of foreign currency fluctuations and acquisitions.  The Company’s management believes that this metric is a useful financial measure for investors in evaluating its operating performance for the periods presented because excluding the effect of currency fluctuations and acquisitions, 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.

The press release also contains disclosure of adjusted diluted net income per share from continuing operations, which is defined, for purposes of this press release, as diluted net income (loss) per share from continuing operations excluding the impact, net of taxes, of impairment charges for goodwill and other intangible assets, charges relating to the early extinguishment of interest rate protection agreements and the Company’s term loan, as well as certain discrete tax benefits, and charges relating to a contemplated acquisition.  The Company’s management views the impairment charges, positive impact of the tax benefits, charges relating to the early

extinguishment of interest rate protection agreements and the Company’s term loan, and acquisition-related charges as anomalous and not indicative of the Company’s ongoing performance. The Company’s management believes adjusted diluted net income per share from continuing operations, when read in conjunction with diluted net income per share from continuing operations, gives investors a useful tool to assess and understand the Company’s overall financial performance, especially when comparing results with previous periods or forecasting performance for future periods, primarily because it excludes items that the Company believes are not reflective of its ongoing operating performance, allowing for a better period-to-period comparison of core operations and growth of the Company.  Additionally, the Company’s management uses adjusted diluted net income per share from continuing operations as one measure of the Company’s performance.  The adjusted diluted net income per share from continuing operations measure does not provide investors with an accurate measure of the actual diluted net income per share from continuing operations earned by the Company and should not be considered a substitute for diluted net income per share from continuing operations 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, organic revenue growth (decline), and adjusted diluted net income per share from continuing operations, 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.
