Tokyo, Japan – August 6, 2007 - Trend Micro (TSE: 4704; the “Company”), a leader in network antivirus and Internet content security software and services, today announced that the forecast of financial results for the second quarter of fiscal year ending December 31, 2007, which were announced on July 25, 2007, has been revised as set forth below:

1. Revision of forecast of financial results for the second quarter of FY2007 (Japan GAAP) (April 1, 2007 to June 30, 2007)

2. Reason for Revision

Due to strong growth of revenues in North America mainly, the Company now forecast the second quarter Net Sales adding over 2.5 billion yen to the previous forecast. On the other hand, costs are slightly below forecasts due to lower stock option expenses as none have been issued during the quarter. Thus, Operating Income is expected to be 48.3% higher than what was previously forecast.

Net income forecast is now expected to be 67.6% above the previous forecast due to higher operating income as described above, as well as higher than expected non-operating income including interest income, etc.
In summary, as a result of this revision, compared to the Second quarter forecast previously published, Net Sales, Operating income and Net income are expected to increase by 11.1%, 48.3%, and 67.6%, respectively.
