These forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from future express or implied results. Although SPX believes that the expectations reflected in its forward-looking statements are reasonable, it can give no assurance that such expectations will prove to be correct. In addition, estimates of future operating results are based on the company’s existing operations and complement of businesses, which are subject to change. Particular risks facing SPX include risks relating to market specific cycles and weather related fluctuations; economic, business and other risks stemming from changes in the economy; legal and regulatory risks; cost of raw materials; pricing pressures; our reliance on U.S. revenues and international operations; our 2015 spin-off transaction; the effectiveness, success, and timing of restructuring plans; our ability to manage changes and measure and estimate the expected revenue, cost and claims associated with our power projects in South Africa; pension funding requirements; liabilities retained in connection with dispositions, and integration of acquisitions.

We believe that these non-GAAP measures are useful to investors in evaluating our operating performance and our management of business from period to period. We have not reconciled non-GAAP financial measures guidance to their nearest GAAP equivalents because we do not provide guidance for items that we do not consider indicative of our on-going performance and that are out of our control and/or cannot be reasonably predicted. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP financial measures is not available without unreasonable effort. March 2019 2
