Exa Reports Fourth Quarter and Fiscal 2013 Financial Results

Fiscal 2013 revenue increases 6% from fiscal 2012 and 10% on a constant currency basis

Burlington, Mass., March 27, 2013 – Exa^® Corporation (NASDAQ: EXA), a global innovator of fluids simulation solutions for product engineering, today announced financial results for the fourth quarter and fiscal 2013, which ended January 31, 2013.

“Revenue of $13.1 million in the fourth quarter was level with the fourth quarter last year,” said Stephen Remondi, President and Chief Executive Officer of Exa. “Customers slowed their discretionary spending slightly more than we had anticipated at the end of the calendar year, resulting in revenue that was at the lower end of our guidance for the fourth quarter. With expenses that were higher than projected, primarily due to shifts in the timing of expenses, we produced a net loss of ($0.3) million, or ($0.03) per share, which corresponds to a non-GAAP net loss of ($0.1) million, or ($0.01) per average weighted share. Over the course of the year, we made significant investments in expanding our sales and field engineering teams to pursue and generate new business in the broader ground transportation and closely adjacent markets. While these investments did not yield the level of return we expected in the fiscal year in terms of revenue growth, we firmly believe that these additional investments position us strongly to improve revenue growth in fiscal 2014 and beyond.

“Looking to fiscal 2014, the expected return of customer spending in the new calendar year appears to be materializing. We saw strong renewal activity among our top customers late in our fourth quarter, and have significantly added to our total customer count. This combined with the highly visible nature of our license model, adds to our confidence in our ability to reaccelerate revenue growth in fiscal 2014. We are focused on generating the return on the investments we made in fiscal year 2013. Our customers continue to recognize significant value from our technology, and we believe we remain firmly positioned to deliver healthy growth over the longer-term.”

Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are presented on a GAAP basis, we disclose revenue on a constant currency basis, 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 revenue on a constant currency basis is GAAP revenue. 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 revenue on a constant currency basis as GAAP revenue, adjusted to reverse the impact of changes in the average exchange rates of currencies in which our international operations generated revenue and incurred expenses.

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, our international operations generate revenue and incur expenses that are denominated in foreign currencies. These amounts could be materially affected by currency fluctuations. Our principal exposures are to fluctuations in exchange rates for the United States dollar versus the Euro, British pound, Japanese yen, Chinese yuan and Korean won. Changes in currency exchange rates that are beyond our control can significantly affect our consolidated results of operations. We believe that disclosure of our revenue on a constant currency basis is useful as an indicator of demand for our solutions independent of the influence of currency exchange fluctuations. 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.
