July 2018 2 Certain statements contained in this presentation that are not historical facts, including any statements as to future market conditions, results of operations, and financial projections, are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and are subject to the safe harbor created thereby. 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 and cost associated with our power projects in South Africa; pension funding requirements; liabilities retained in connection with dispositions; and integration of acquisitions and achievement of anticipated synergies. More information regarding such risks can be found in SPX’s Annual Report on Form 10-K and other SEC filings. Statements in this presentation are only as of the time made. All references to 2018 guidance reflect the company’s view of expected full-year results at the time this guidance was issued and/or updated in press releases and presentations made available in the investor relations section of the website SPX.com on July 2, 2018, June 7, 2018 and May 3, 2018. SPX disclaims any responsibility to update or revise such statements except as required by regulatory authorities. This presentation includes forward-looking non-GAAP financial measures, including “Adjusted earnings per share,” “pro form Adjusted earnings per share,” “EBITDA (Core)” of each segment, “Engineered Solutions (Core) segment income,” “Detection & Measurement adjusted segment income,” “Core Revenue,” “Core Segment Income Margin,” and “Adjusted Operating Margin.” Each of these non-GAAP measures excludes items, which would be included in our financial measures presented in accordance with United States generally accepted accounting principles (“GAAP”), that we do not consider indicative of our on-going performance and are calculated by the company in a manner consistent with the presentation of similarly titled measures included in its May 3, 2018 press release announcing the results of operations for the first quarter of 2018, except that EBITDA (Core), which is not presented in such press release, is calculated by adding for each respective segment, its depreciation and amortization expense to segment income (for the HVAC segment), Detection & Measurement adjusted segment income (for the Detection & Measurement segment), and Engineered Solutions (Core) segment income (for the Engineered Solutions segment), and EBITDA margin, which is for each segment such segment’s EBITDA (Core) divided by segment revenues (for the HVAC and Detection & Measurement segments), and Engineered Solutions (Core) revenues (for the Engineered Solutions segment. Because of the forward-looking nature of these items, it is impractical to present a quantitative reconciliation of such measure to a comparable GAAP measure, and accordingly no such GAAP measure is being presented. “Core” and “Engineered Solutions (Core)” results in this presentation are non-GAAP financial measures that exclude the results of the South African projects.
