Unica Announces Results for Fiscal 2006 Third Quarter

WALTHAM, Mass — August 3, 2006 – Unica^® Corporation (Nasdaq: UNCA), a leading global provider of Enterprise Marketing Management (EMM) solutions, today announced financial results for its fiscal third quarter ended June 30, 2006.

For the third quarter of fiscal 2006, Unica reported record total revenue of $21.7 million, an increase of 33% compared with the third quarter of fiscal 2005. License revenue increased 42% to $10.5 million and maintenance and services revenue increased 25% to $11.2 million from the prior year quarter. For the third quarter of fiscal 2006, maintenance revenue was $8.3 million, an increase of 28% from the prior year quarter, and services revenue was $2.9 million, an increase of 17% from the prior year quarter.

Yuchun Lee, chief executive officer of Unica Corporation, stated, “I am very pleased with the Company’s performance in the third fiscal quarter, which was highlighted by record license revenue and very strong growth.” Lee added, “Unica is consistently recognized as the leader in the EMM market, and we are making the necessary investments to maintain and extend this leadership position as market awareness and demand increases. We believe that other vendors cannot match Unica’s leading technology and ability to meet the market’s growing desire to purchase a broad EMM suite from a single vendor. Moreover, the strength of each application within our suite is evidenced by our leadership position in campaign management coupled with the growing traction of our MRM and internet marketing solutions.”

For the third quarter of fiscal 2006, Unica reported a loss from operations, in accordance with generally accepted accounting principles (GAAP), of $238,000. GAAP loss from operations includes $1.0 million in non-cash stock compensation expense and $721,000 in amortization of acquired intangibles. GAAP net income for the fiscal third quarter of 2006 was $215,000, resulting in GAAP net income per diluted share of $0.01, compared to $0.05 in the same period last year.

For the third quarter of fiscal 2006, non-GAAP income from operations, which excludes stock-based compensation expense and amortization of acquired intangibles, was $1.5 million, or a non-GAAP operating margin of 7%. Based on an estimated 29% non-GAAP effective tax rate, non-GAAP net income was $1.4 million in the third quarter of fiscal 2006, resulting in non-GAAP diluted earnings per share of $0.07, compared to $0.08 in the same period last year.

Non-GAAP diluted earnings per share assumes the conversion of Unica’s preferred stock into common shares for the fiscal third quarter of 2005. A reconciliation of GAAP to non-GAAP results has been provided in the financial statement tables included in this press release. An explanation of these measures is also included below under the heading “Non-GAAP Financial Measures.”

As of June 30, 2006 Unica had cash, cash equivalents, and short-term investments of $42.1 million, an increase from $39.4 million at March 31, 2006. The Company generated $1.7 million in cash from operations in the three months ended June 30, 2006, and $9.2 million for the first nine months of fiscal 2006. At June 30, 2006, deferred revenue was $31.4 million, representing an increase of 32% on a year-over-year basis.

Ralph Goldwasser, chief financial officer of Unica, stated, “In addition to delivering strong top line growth, we are very pleased with the company’s ability to generate strong cash flow while making investments to deliver on our EMM vision.”

Additional Third-Quarter Business Highlights:

In addition, the Company added several new web-analytics customers, including, Procter & Gamble, Honda of Canada, ABN AMRO, Foxwoods Resort Casino and Columbia University.

Fourth Quarter of Fiscal 2006

• Non-GAAP Operating Income: Expected to be between $2.2 million and $2.3 million with a certain amount of variability

Non-GAAP Financial Measures

Unica has provided in this press release selected financial information that has not been prepared in accordance with GAAP. This information includes historical and estimated future non-GAAP operating income, net income, effective tax rate, and earnings per share.

Unica uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating Unica’s ongoing operational performance. Unica believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends, and in comparing its financial results with other companies in Unica’s industry, many of which present similar non-GAAP financial measures to investors. Specifically, on both a historic and a forward-looking basis, these non-GAAP measures exclude:

• Expense associated with the write-off of in-process research and development and amortization of intangible assets related to acquisitions, as exclusion of these expenses allows comparisons of operating results that are consistent over time for both the Company’s newly acquired and long-held businesses and with both acquisitive and non-acquisitive peer companies.

• Expense associated with stock-based compensation related to stock options, the Company’s employee stock purchase plan and restricted stock units because, while stock-based compensation is a significant ongoing expense affecting the Company’s results of operations, the Company’s management excludes stock-based compensation from the Company’s forecasting and planning process used to allocate resources. Additionally, the Company believes that excluding this expense could be helpful in comparing the Company’s financial results to previous periods because prior to the adoption of FAS 123R on October 1, 2005, stock option expense was recorded in the statement of operations based on intrinsic value, not fair value. Finally, because of varying available valuation methodologies, subjective assumptions and the variety of award types, the Company believes that excluding stock-based compensation may enable useful comparisons of the Company’s operating results to its competitors.

Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure as detailed above. As previously mentioned, a reconciliation of GAAP to non-GAAP results has been provided in the financial statement tables included in this press release.

Non-GAAP effective tax rates for the three and nine months ending June 30, 2006 were 29% and 32%, respectively versus GAAP effective tax rates of (7%) and 74%, reflecting the impact of discrete tax items. The non-GAAP tax provision excludes impact from the write-off of in-process research and development, amortization of intangibles arising from business combinations and stock-based compensation expense.

(3)

Non-GAAP weighted average shares outstanding for the three and nine months ended June 30, 2005 assumes the conversion of Unica’s preferred stock into 4,083 shares of common stock. As a result, earnings applicable to common shareholders are not affected by the accretion of preferred stock dividends, or allocation of earnings to preferred stockholders, as in the computation of GAAP EPS.
