0. Bottom line first

Semiconductor equipment results appear to be starting now. However, full-scale mass production still seems to be delayed. I do not think this is a stock to buy simply based on earnings, so I am continuing to follow it and waiting for an additional-buying point.

1. Change Confirmed in Q1

Official fact: The source notes that Q1 alone filled as much as last year's equipment results, likely for glass substrates, and that the related share changed from 2% to the 30% range.

2. I Am Not Judging Only by Earnings

Interpretation: It is positive that semiconductor equipment revenue is starting to show, but full-scale mass production appears to be delayed. For that reason, I do not think this is a stock to buy simply on this quarter's numbers.

The numbers are beginning to improve, but additional buying depends on mass-production timing and follow-up flow.

3. Response From Here

  • Check whether semiconductor equipment results continue in the next quarter.
  • Watch whether the share change, estimated to be for glass substrates, persists.
  • Continue following whether full-scale mass production is delayed and for how long.
  • Avoid rushing based only on earnings and wait for an additional-buying point.
