Tokyo, Japan - August 4, 2010 - 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, 2010, which were announced on May 11, 2010, has been revised as set forth below:

1. Revision of forecast of financial results for the second quarter of FY2010

(April 1, 2010 to June 30, 2010)

2. Reason for Revision

The rebate (a deduction item from sales) for consumer business in Japan is now forecasted to be much higher than we expected, and also net sales in other foreign regions are expected to be slightly lower. The net impact is likely to reduce the net sales forecast by 600 million yen.
At the same time, we expect that the costs will be in line with our original forecasts, and software depreciation is expected to be slightly higher than our expectations - The total costs in the quarter are thus likely to exceed the original projection by 200 Mn Yen.
 In summary, as a result of this revision, compared to the first quarter forecast previously published, Net Sales, Operating income, Ordinary income and Net income are expected to decrease by 2.5%, 12.7%, 12.3% and 17.9% respectively.
