Exa Reports Second Quarter Fiscal 2013 Financial Results

Burlington, Mass., September 6, 2012 – Exa^® Corporation (NASDAQ: EXA), a global innovator of fluids simulation solutions for product engineering, today announced financial results for the second quarter of fiscal 2013, which ended July 31, 2012.

“We are pleased with the company’s second quarter performance and strong financial results in our first quarter as a public company,” said Stephen Remondi, President and Chief Executive Officer of Exa. “Our differentiated technology enables customers to perform accurate and detailed aerodynamic, thermal and acoustic simulations of their designs to improve product quality and performance while increasing efficiency of their design process. During the second quarter we made significant progress in deploying PowerFLOW deeper into our target markets. Existing customers expanded usage of PowerFLOW across their global engineering footprints and added simulation capacity as they begin to leverage advanced optimization techniques to seek further improvements in their designs. Both new and existing customers added simulation capabilities to tackle new challenges such as the reduction of fan noise and to meet tougher emissions regulations. Outside of ground transportation, we continued to make strong progress with early adopters in the aerospace market.”

“We believe we are still in the early stages of penetrating the markets available to us for simulation based solutions to replace costly and time-consuming physical prototypes. Our strategy to invest in our R&D team and field organization continues to progress and we believe that continued investments will help increase the value we can deliver to our customers and as a result solidify our position as a leading provider of simulation-based design technology, enabling us to continue our track record of profitable growth.”

Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are presented on a GAAP basis, we disclose Non-GAAP Income from Operations, Non-GAAP Net Income, Non-GAAP Net Income per Diluted Share and Adjusted EBITDA. These non-GAAP measures are not in accordance with, or an alternative for, amounts determined in accordance with generally accepted accounting principles in the United States. The GAAP measure most comparable to Non-GAAP Income from Operations is GAAP income from operations, The GAAP measure most comparable to Non-GAAP Net Income and Adjusted EBITDA is GAAP net income. The GAAP measure most comparable to Non-GAAP Net Income per Diluted Share is GAAP Net Income per Diluted Share. A reconciliation of these non-GAAP financial measures to the corresponding GAAP measure is included below.

We define Non-GAAP Net Income as net income, excluding the after tax impact of stock-based compensation expense and the amortization of acquired intangibles. We define EBITDA as net income, excluding depreciation and amortization, interest expense, other income (expense), foreign exchange gain (loss) and provision for income taxes, and we define Adjusted EBITDA as EBITDA, excluding non-cash share-based compensation expense.

Our management uses these non-GAAP measures when evaluating our operating performance and for internal planning and forecasting purposes. We believe that these measures help indicate underlying trends in our business, are important in comparing current results with prior period results, and are useful to investors and financial analysts in assessing our operating performance. For example, management considers Adjusted EBITDA to be an important indicator of our operational strength and the performance of our business and a good measure of our historical operating trends. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, or superior to, the financial information presented in accordance with GAAP and, in particular, should not be considered a measure of our liquidity. There are significant limitations associated with the use of non-GAAP financial measures. Further, these measures may differ from the non-GAAP information, even where similarly titled, used by other companies and therefore should not be used to compare our performance to that of other companies. Investors should carefully consider the attached reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures.
