Zix Corporation Announces Second Quarter 2006 Financial Results

DALLAS — August 8, 2006 —Zix Corporation (ZixCorp^®), (Nasdaq: ZIXI), the leader in hosted services for email encryption and e-prescribing, today announced financial results for the second quarter ended June 30, 2006. ZixCorp recorded second quarter revenues of $4.2 million and recorded a second quarter 2006 net loss of $5.1 million, or 9 cents loss per share, compared with revenues of $3.4 million and a net loss of $8.9 million, or 28 cents loss per share, in the corresponding quarter in 2005.

“I’m pleased to report a record $1.1 million gross margin for the company in the second quarter, an impressive achievement when compared to the negative gross margin from just a year ago,” said Rick Spurr, chairman and chief executive officer for ZixCorp. “We are making great strides toward improving the financial condition of the company, driven in particular by the continuing growth in our email encryption business. However, we’re not satisfied yet with the pace of progress in our financials. We intend to accelerate this improvement by making further moves beyond those cost-cutting actions already announced this past quarter to ensure that the company has sufficient capital to reach cash flow breakeven and is well-positioned to take advantage of the future growth potential in each of its core businesses.”

Q2 Corporate Highlights

• Raised $11.8 million ($10.9 million net of transaction fees) in a private placement of its common stock and related warrants, and ended the quarter with $19.6 million in unrestricted cash, which was within guidance

• Repaid the remaining $5 million of its convertible debt in an ongoing effort to improve the balance sheet

• Announced and began to implement cost-cutting measures to increase operational efficiency; specifically, eliminating 15 percent of the workforce and a similar reduction in non-headcount related expenses. The Company is now planning additional cuts to increase the targeted cost reduction to 25 percent of total expenses, which is expected to remove an estimated $9-$11 million from the 2007 cost structure

Q2 Business Highlights

e-Prescribing

• Announced three significant new payor contracts in the second quarter with L.A. Care Health Plan, the nation’s largest public health plan, Blue Cross and Blue Shield of North Carolina and an exclusive contract with Blue Cross and Blue Shield of Louisiana

• Processed 1.3 million e-scripts during the quarter, an increase of 117 percent over the same period last year

• Announced an agreement with Per-Se Technologies to expand ZixCorp’s market reach, including access to Prime Therapeutics, a PBM aligned with nine Blue Cross and Blue Shield plans

• Deployed 445 doctors, which was near the top end of guidance and included completing the deployment of pilots for the Aetna and Independence Blue Cross contracts

Email Encryption:

• Produced one of the company’s strongest new first-year order totals at $1.4 million in Q2, up more than 30 percent over Q1 2006, and the renewal rate for customer contracts this quarter was 100 percent. Total email encryption orders were $5.3 million, the second highest level in the Company’s history

• Launched ZixDirect™, a zero footprint delivery service which “pushes” encrypted email directly to the recipient’s inbox, and saw an immediate impact on existing and new customer sales in Q2 orders

• Named a winner of the Global Excellence in Encryption Customer Trust 2006 Award for ZixCorp’s email encryption service byInfo Security Products Guide

• Reached additional milestones during the second quarter, including:

• 1 in 8 hospitals in the U.S. use ZixCorp email encryption services

• 1 in 3 Americans with health insurance is covered by a carrier who uses ZixCorp services

• 40 million emails scanned every month for policy driven content

ZixData Center™

• Transaction throughput consisting of both email messages and electronic prescriptions more than doubled from a year ago, with 533 million transactions in Q2 2006

Financial Highlights for the Quarter

Revenues:Revenues were $4.2 million in the second quarter 2006, which was a 22 percent increase over the second quarter 2005. When the revenues for divested products are removed and only the company’s current products remain, the total revenues increased by 27 percent in the second quarter 2006 compared with the second quarter 2005. The company’s email encryption services increased revenue year-over-year by 38 percent, while e-prescribing declined by 5 percent. Email encryption’s rise was due to the record orders the company experienced in the first and second quarters of 2005, which are now fully in service and being recognized into revenue. e-Prescribing revenues declined due to several factors, including the impact of changes in the contract terms which resulted in all revenue on new contracts being recognized ratably over the contract term, the inclusion of more performance-based contract requirements, and the drop off of revenues from the Wellpoint initiative. The company’s order backlog (contractually bound service contracts that represent future revenue to be recognized as the services are provided) was $25 million on June 30, 2006.

Gross Margin:Company-wide gross margin grew by $1.2 million, compared with the second quarter 2005, to reach a record $1.1 million for the second quarter 2006, or 27 percent of revenues. The gross margin contribution from email encryption services was $2.0 million (61 percent), while gross margin for e-prescribing services remained negative, at an estimated negative $0.9 million for the second quarter 2006. The company-wide gross margin for the same period in 2005 was negative $0.1 million or negative 2 percent of revenues, with the gross margin for email encryption estimated to be $1.1 million (45 percent) in that quarter. The year-on-year improvement in the gross margin for email encryption services was caused by continued revenue growth (38 percent over Q2 2005) combined with a slightly lower cost of revenues. The gross margin in e-prescribing was essentially flat year-on-year.

R&D and SG&A Expenditures:In the second quarter 2006, the company’s research and development (R&D) expenditures and its sales, general, and administrative (SG&A) expenditures increased by $0.1 million when compared with the same period in 2005, representing an increase of one percent. The spending declined as a result of divested products and general cost-cutting, with an offsetting increase of $0.7 million from the implementation of FAS 123R (expensing of stock options).

Other Income and Expense:In the second quarter 2006, the company recorded $1.9 million of other income. The Company recorded a non-cash gain of $2.9 million on a change in fair value of derivative financial instruments. This gain was partially offset by a $0.9 million loss on extinguishment of the convertible debt and $0.1 million of net interest expense. Regarding the gain on derivative instruments, the company accounted for the various components of the April 5, 2006 private placement transaction as derivative financial instruments. This treatment will cause a mark-to-market valuation of the derivative components each quarter, which can result in significant non-cash gains or losses for a period of up to two years. The loss on extinguishment of debt resulted from writing-off the balances of unamortized discounts and financing costs on the note ($0.7 million non-cash items) and the payment of an early payment premium ($0.2 million cash item). More detailed information on these items will be available in the Company’s Form 10-Q for the period ended June 30, 2006.

Net Loss:ZixCorp recorded a net loss of $5.1 million for the second quarter 2006 versus a net loss of $8.9 million in second quarter 2005. The $3.8 million decline in the net loss is from the $1.2 million improvement in the gross margin, net improvement from $1.1 million in various one-time events, primarily the Other Income and Expense items mentioned above, and a reduction of net interest expense of $1.5 million.

Cash Utilization:Unrestricted cash and cash equivalents as of June 30, 2006, was $19.6 million, a $5.4 million increase from March 31, 2006. The primary components of this increase were $10.9 million net cash inflow to the Company from the private placement of its common stock and related warrants (after transaction fees), less net cash used by operating activities in the second quarter 2006 of $5.1 million.

Debt Payoff:The Company paid off the remaining balance of its convertible debt with a final payment of $5.3 million, including a prepayment premium and accrued interest. The debt payoff resulted in a release of $5.0 million in restricted cash held in a collateral account. The Company also recognized a $0.9 million loss ($0.7 million of which was non-cash) on the debt extinguishment as unamortized financing costs and discounts were eliminated.
