ZixCorp's Preliminary Results for Fourth Quarter 2009 Point to Best Quarter in Company History

Zix Corporation (ZixCorp®), (Nasdaq: ZIXI), the leader in email encryption services, today offered a financial update on the fourth quarter 2009 and provided guidance for 2010. Current estimates indicate the Company has achieved a record for new first-year orders in its Email Encryption business with $2.4 million for the fourth quarter of 2009, 61 percent higher than the fourth quarter of 2008. Total orders for Email Encryption were $11.3 million in the fourth quarter, also a record for the Company. The Company's renewal rate in the fourth quarter for Email Encryption customers was 93 percent, resulting in a 91 percent overall renewal rate for calendar year 2009. The Company's ending cash balance at December 31, 2009 is estimated to be $13.2 million. ZixCorp also affirmed its fourth quarter 2009 guidance for revenue of $7.9 to $8.1 million and adjusted non-GAAP earnings of $0.01 to $0.02 per share.

In addition, ZixCorp announced that it expects 2010 to be the first year of profitability, on both a GAAP and an adjusted non-GAAP basis, in the Company's history. The Company projects its full-year 2010 revenues to be between $34 and $36 million, of which e-Prescribing revenues during the wind-down of this business would comprise $2.1 to $2.6 million. For full-year 2010, basic GAAP earnings per share are projected to be between $0.06 and $0.09, and fully-diluted earnings per share are projected to be between $0.05 and $0.08, assuming 67 million shares outstanding on a fully diluted basis. Fully diluted non-GAAP adjusted earnings per share, which are adjusted primarily for non-cash stock-based compensation and non-recurring expense items, are projected to be between $0.08 and $0.11.

"ZixCorp had a tremendous fourth quarter in our core Email Encryption business, smashing our previous record for new first-year orders by 35 percent, and, if our current estimates hold true, setting a record for overall revenue in the process," said Rick Spurr, ZixCorp's Chairman and Chief Executive Officer. "We believe we can build on this momentum for a strong year in 2010, and we expect this year to be our first year ever of profitability as a company. We expect healthy growth in orders this year to drive continued growth in revenues for Email Encryption, partially offset by the expected decline in e-Prescribing revenues in 2010 as we exit that business. With the expansion of HIPAA regulations under the American Recovery and Reinvestment Act of 2009 driving strong demand in healthcare where ZixCorp is the recognized leader in encrypted email, the ever-increasing recognition of the need for securing sensitive information, the superiority of our Software as a Service ("SaaS") offering, the consolidation in the email encryption industry around just a few competitors, and our ability to increase investment in targeted opportunities, I believe this business will perform well in 2010 and allow us to achieve this significant milestone."

A component of the Company's 2010 forecast is management's expectation that the e-Prescribing business will be breakeven to slightly profitable on a GAAP basis throughout the wind-down of this business during 2010. The Company has targeted December 31, 2010 as the official termination date for this business, due in large part to the expiration of ongoing contractual commitments by that date. ZixCorp has reduced its e-Prescribing staff to 10, and, based on projections for renewals to be just below historical rates in the first quarter of 2010 and then decline significantly as the end of 2010 approaches, the Company believes its e-Prescribing revenues should at least cover the costs incurred by this business during the wind-down process. On a cash basis, however, total outlays through the end of 2010 associated with the wind-down of the e-Prescribing business are projected to be between $1.0 million and $1.3 million. In addition, the Company expects that approximately $0.8 million of annual expenses projected to be allocated to the e-Prescribing business in 2010, including approximately $0.4 million of corporate costs such as insurance and facility costs and approximately $0.4 million of personnel-related costs for employees who provide services for both lines of business, will remain with the Company after the exit from the e-Prescribing business has been completed. Additional details on the wind-down process will be provided on the conference call to discuss the 2009 results.
