Ems (ELMG) 8-K Results of Operations and Financial Condition

Exhibit 99.1

EMS Technologies Neil Mackay - President & CEO Gary Shell - Sr. VP & CFO

Forward Looking Statements EMS has included forward-looking statements in this investor presentation. All statements, other than statements of historical fact, included in this presentation that address activities, events or developments that we expect or anticipate will or may occur in the future, or that depend upon future events, including such matters as our expectations with respect to future financial performance, future capital expenditures, business strategy, competitive strengths, goals, expansion, market and industry developments, and the growth of our businesses and operations, are forward-looking statements. For example, words such as "may", will", "would", "should", "estimates", "targets", "predicts", "projects", "potential", "continues", "strategy", "believes", "anticipates", "plans", "expects", "intends" and similar expressions are intended to identify forward-looking statements. In particular, this investor presentation includes financial projections, which provide management's current expectations with respect to our future financial performance over an extended period of time. Actual results could differ materially from those suggested in our projections or other forward-looking statements included in this investor presentation as a result of a variety of factors. Such factors include, but are not limited to: economic conditions in the U.S. and abroad and their effect on capital spending in our principal markets; difficulty predicting the timing of receipt of major customer orders, and the effect of customer timing decisions on our results; our successful completion of technological development programs and the effects of technology that may be developed by, and patent rights that may be held or obtained by, competitors; U.S. defense budget pressures on spending priorities and contract-award schedules; uncertainties inherent in the process of converting contract awards into firm contractual orders in the future; volatility of foreign currency exchange rates relative to the U.S. dollar and their effect on purchasing power by international customers, and on the cost structure of our operations outside the U.S., as well as the potential for realizing foreign exchange gains and losses associated with assets or liabilities denominated in foreign currencies; successful resolution of technical problems, proposed scope changes, or proposed funding changes that may be encountered on contracts; changes in our consolidated effective income tax rate caused by the extent to which actual taxable earnings in the U.S., Canada and other taxing jurisdictions may vary from expected taxable earnings, changes in tax laws, and the extent to which deferred tax assets are considered realizable; successful transition of products from development stages to an efficient manufacturing environment; changes in the rate at which our products are returned for repair or replacement under warranty; customer response to new products and services, and general conditions in our target markets (such as logistics, space-based communications and commercial and private aviation), and whether these responses and conditions develop according to our expectations; the increased potential for asset impairment charges as unfavorable economic or financial market conditions or other developments might affect the estimated fair value of one or more of our business units; the success of certain of our customers in marketing our line of high-speed commercial airline communications products as a complementary offering with their own lines of avionics products; the availability of financing for various mobile and high-speed data communications systems; risk that unsettled conditions in the credit markets may make it more difficult for some customers to obtain financing and adversely affect their ability to pay, which in turn could have an adverse impact on our business, operating results, and financial condition; development of successful working relationships with local business and government personnel in connection with the distribution and manufacture of products in foreign countries; the demand growth for various mobile and high-speed data communications services; our ability to attract and retain qualified senior management and other personnel, particularly those with key technical skills; our ability to effectively integrate our acquired businesses, products or technologies into our existing businesses and products, and the risk that any such acquired businesses, products or technologies do not perform as expected, are subject to undisclosed or unanticipated liabilities, or are otherwise dilutive to our earnings; the potential effects, on cash and results of discontinued operations, of final resolution of potential liabilities under warranties and representations that we made, and obligations assumed by purchasers, in connection with our dispositions of discontinued operations; the availability, capabilities and performance of suppliers of basic materials, electronic components and sophisticated subsystems on which we must rely in order to perform according to contract requirements, or to introduce new products on the desired schedule; uncertainties associated with U.S. export controls and the export license process, which restrict our ability to hold technical discussions with customers, suppliers and internal engineering resources and can reduce our ability to obtain sales from customers outside the U.S. or to perform contracts with the desired level of efficiency or profitability; and our ability to maintain compliance with the requirements of the Federal Aviation Administration and the Federal Communications Commission, and with other government regulations affecting our products and their production, service and functioning. Undue reliance should not be placed on any forward-looking statements, which are based on current expectations. Further, forward-looking statements speak only as of the date they are made, and EMS' management undertakes no obligation to update publicly any of them in light of new information or future events. Given the inherent uncertainty involved in the presentation of our financial projections, we advise you to review the projections disclaimer on the next page of this investor presentation for a detailed discussion of the factors that could cause our actual results to differ materially from our projected results and the limitations on the use of projections. 2

EMS does not routinely make public projections as to future performance, earnings or other results beyond the current fiscal year due to the unpredictability of the underlying assumptions and estimates. However, in connection with this investor presentation, we have included our financial goals to supplement our discussion of our plans for the future of our business. The financial forecasts regarding our goals for future operations cover periods through fiscal 2014 (the "Financial Goals"). The Financial Goals were prepared by, and are the responsibility of, EMS' management. The Financial Goals do not necessarily comply with published guidelines of the Securities and Exchange Commission, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts, or generally accepted accounting principles. KPMG LLP, EMS' independent registered public accounting firm, has not audited, reviewed, compiled or performed any procedures with respect to the Financial Goals and does not express an opinion or any form of assurance related thereto. Importantly, the Financial Goals reference Adjusted EBITDA, which is a non-GAAP financial measure. As indicated, the Financial Goals represent our internal goals for our future financial performance versus a detailed line item financial projection. As such, we have not included a reconciliation bridging our earnings goals to our Adjusted EBITDA goals. The Financial Goals, while presented within a specified range, necessarily were based on numerous variables and assumptions that are inherently uncertain and many of which are beyond the control of EMS' management. Because the Financial Goals cover multiple years, by their nature, they become subject to greater uncertainty with each successive year. The assumptions upon which the Financial Goals were based necessarily involve judgments with respect to, among other things, future economic, competitive and regulatory conditions and financial market conditions, all of which are difficult or impossible to predict accurately and many of which are beyond EMS' control. The Financial Goals also reflect assumptions as to certain business decisions that are subject to change. The Financial Goals are also predicated on the successful execution of our business strategies discussed in this investor presentation. Important factors that may affect actual results and result in the Financial Goals not being achieved include, but are not limited to, the factors highlighted in discussion regarding forward-looking statements at the beginning of this investor presentation, as well as the other risk factors described in EMS' annual report on Form 10-K for the year ended December 31, 2009, subsequent quarterly reports on Form 10-Q and current reports on Form 8-K, all of which risk factors are hereby incorporated by reference into this investor presentation. In addition, the Financial Goals may be affected by EMS' ability to achieve strategic goals, objectives and targets over the applicable periods. Accordingly, there can be no assurance that the Financial Goals will be realized, and actual results may vary materially from those shown. Neither EMS nor any of its affiliates can give any assurance that actual results will not differ from the Financial Goals, and none of them undertakes any obligation to update or otherwise revise or reconcile the Financial Goals to reflect circumstances existing after the date the Financial Goals were generated or to reflect the occurrence of future events even if any or all of the assumptions underlying the Financial Goals are shown to be in error. EMS does not intend to make publicly available any update or other revision to the Financial Goals, except as otherwise required by law. Neither EMS nor any of its affiliates has made or makes any representation to any EMS shareholder or other person regarding the ultimate performance of EMS compared to the information contained in the Financial Goals or that the Financial Goals will be achieved.
