Lee, MA—March 28, 2012—Wave Systems Corp. (NASDAQ: WAVX) today reported financial results for its fourth quarter (Q4) and year ended December 31, 2011, having previously postponed its year-end reporting due to the discovery of certain pre-acquisition accounting errors in the financial statements of its Safend Ltd. subsidiary acquired September 22, 2011. Wave expects to file its annual report on Form 10-K on or before March 30, 2012.

Wave CEO Steven Sprague, commented, “2011 was a pivotal year for Wave as we built the business across several important fronts, deepening our engagement into exciting new product markets and geographies. As a result of significant enterprise deals closed in Europe, we expanded our presence in the region, adding a team of seasoned sales professionals and establishing offices in France, Germany and the United Kingdom to support our market outreach. Through our acquisition of Safend, we rounded out our product portfolio with a robust set of award-winning Data Loss Prevention (DLP) products, added to our roster of customers, expanded our engineering and sales teams and secured a foothold in Israel and other global markets. While the pre-acquisition accounting errors we have reported for Safend are regrettable, they do not change our view of the importance of this acquisition for Wave.

“We took an equally forward-leaning stance on the product development front, investing aggressively to position Wave to address a range of additional potential opportunities, including our service contract announced yesterday with the U.S. Army. In response to the emergence of sophisticated viruses such as Stuxnet, we were the first to market with a product for the early detection of BIOS-level threats, Wave Endpoint Monitor. In the mobile space, we joined with partners Trusted Logic Mobility and ARM to create an industry-first mobile security demonstration in which an Android phone was used as an authentication token. We also extended our management solutions into the Cloud with the launch of Wave Encryption Service, and today we are working on a next-generation, feature-rich cloud service that we plan to make commercially available later this year.

“The coming launch of the Windows 8 operating system is a major development because of its increased emphasis on trusted computing. Microsoft has made security a primary focus for Windows 8 and is integrating hardware-level support for access control, encryption and the early detection of malware using trusted computing security. These capabilities should provide additional opportunities for the adoption of Wave’s enterprise management solutions to manage such functions.

“Finally, in the coming weeks you’ll hear more from Wave in the consumer space, as we plan the ‘beta’ launch of a service we’ve developed called scrambls. Demonstrations started in November and have yielded strong interest and positive feedback from a broad array of users. The solution leverages Wave’s deep expertise in encryption and data protection to return control of content shared over social networks to individual creators.

“In summary, we believe Wave is at the forefront of important innovations for cyber security, and we continue to actively pursue a growing range of market opportunities. We believe that investments in these initiatives, though challenging to near-term profitability, are essential to solving key security challenges, supporting our partners and positioning Wave for long term success.”

Financial Review

Wave’s Q4 ‘11 total net revenues rose 57% to $11.0 million compared to $7.0 million in Q4 ‘10 and rose 16% over Q3 ‘11 net revenues of $9.5 million. The increase in total net revenues was primarily the result of the recognition of $2.4 million of revenue from “large” enterprise customers and $1.6 million of Safend net revenue for the full quarter. Wave recognizes “large” enterprise orders (5,000 or more licenses) as earned revenue ratably over the arrangement’s maintenance term which is typically twelve months.

Total billings declined to $11.5 million in Q4 ‘11, versus $14.2 million in Q4 ‘10 (which included $8.1 million in billings related to a large global automaker order) but increased over Q3 ‘11 total billings of $6.4 million. Q4 ‘11 total billings included $1.7 million from one of the world’s leading international oil and gas companies and a full quarter of Safend billings. Total net revenues are reconciled to total billings below.

Wave continues to accelerate investments in sales and marketing and R&D initiatives in line with the strategy management has articulated over the past several quarters. The investments are intended to maintain Wave’s market leadership, to build its technology and product portfolios, to expand into new areas of growth such as mobile security and to drive increased awareness and customer engagement on a global basis.

Principally related to increased engineering and sales & marketing activity and headcount increases, as well as the addition of Safend operations in late September 2011, Wave’s aggregate SG&A and R&D expenses in Q4 ‘11 rose 30% or $3.3 million over Q3 ‘11 levels, $2.6 million of which was attributable to Safend. Wave’s 2011 SG&A and R&D expenses rose $15.9 million or 56% over 2010 levels, reflecting the company’s substantial expanded OEM, product and geographic engagement, as well as $2.8 million of SG&A and R&D expenses attributable to Safend.

Non-cash stock-based compensation expense nearly doubled to $1.4 million in Q4 ‘11 as compared to Q4 ‘10 and rose 6% over the Q3 ‘11 level. The increase reflects the substantial expansion of Wave’s headcount over the past year, as stock-based compensation remains an important component of Wave’s company-wide recruitment and retention strategy. In addition, Wave recorded approximately $1.0 million of expense

during Q4 ‘11 and the full year 2011 to reflect adjustments to the purchase accounting for the Safend acquisition.

Wave recorded a Q4 ‘11 net loss of $4.9 million, or $0.05 per basic and diluted share, compared to a Q4 ‘10 net loss of $1.2 million, or $0.01 per basic and diluted share, and a Q3 ‘11 net loss of $1.8 million, or $0.02 per basic and diluted share. Per share figures are based on a weighted average number of basic shares outstanding during Q4 ‘11, Q4 ‘10 and Q3 ‘11 of 88.5 million, 81.2 million and 83.7 million, respectively.

Wave reports EBITDAS, a non-GAAP measure defined as earnings before interest income (expense), income taxes, depreciation and amortization and stock-based compensation expense, in order to highlight its operational performance on a cash-flow basis. Wave recorded negative EBITDAS of $2.8 million in Q4 ‘11, compared with negative EBITDAS of $0.3 million in both Q4 ‘10 and Q3 ‘11. A reconciliation of net loss to EBITDAS is presented below.

Wave’s cash and cash equivalents were $3.4 million at December 31, 2011 compared to $3.6 million at December 31, 2010 and $6.9 million at September 30, 2011. As of December 31, 2011, Wave’s total current assets were $11.4 million and total current liabilities — including the current portion of deferred revenue of $6.6 million— were $13.4 million. In late January 2012 Wave entered into an At The Market Issuance (ATM) sales agreement with investment banking firm MLV & Co. (the “Sales Agent”), pursuant to which Wave may issue and sell up to $20 million of its Class A common stock from time to time through July 2014. Such sales would be pursuant to an effective shelf registration statement. As of March 26, 2012, Wave has issued approximately 1.1M shares of its common stock through the ATM structure at an average price of $2.185 per share, raising net proceeds of approximately $2.4M after deducting offering costs of approximately $73,000.

Non-GAAP Financial Measures:

As supplemental information, we provide the non-GAAP performance measures that we refer to as total billings and EBITDAS.  Total billings is provided in addition to, but not as a substitute for, GAAP total net revenues.  Total billings means the sum of total net revenues determined in accordance with GAAP, plus the increase or minus the decrease in deferred revenue.  We consider total billings an important measure of our financial performance, as we believe it best represents the continued increase in our software license upgrades.  Total billings is not a measure of financial performance under GAAP and, as calculated by us, may not be consistent with computations of total billings by other companies.   EBITDAS is defined as net income (loss) before interest income (expense), income taxes, depreciation and amortization and stock-based compensation.  EBITDAS should not be construed as a substitute for net income (loss) or net cash provided by (used in) operating activities (all as determined in accordance with GAAP) for the purpose of analyzing our operating performance, financial position and cash flows, as EBITDAS is not defined by GAAP.  However, we regard EBITDAS as a complement to net income (loss) and other GAAP financial performance measures, including an indirect measure of operating cash flow.
