2. Reasons for the revision

Resonac has revised its consolidated earnings forecast for the second quarter (interim period). Revenue is now expected to exceed the previous forecast, mainly reflecting increased sales volumes for advanced semiconductor applications in the Semiconductor and Electronic Materials segment.

In line with this, core operating profit and other profit items are also expected to exceed the previous forecast. The full-year consolidated earnings forecast has been left unchanged, given the difficulty in reasonably estimating performance for the second half amid continued uncertainty in the global environment.
