Inside information is defined as follows.
Didn’t Atte fear a share price reaction there, so it can be read between the lines that they were in a very gray area, even if he didn’t want to call it inside information.
Based on the definition, I would call this inside information myself. It was certainly to be expected that there would be a price impact when the CFO, who served as a key person in a company in crisis, leaves in the middle of an integration process while the market is already nervous about whether a profit warning (negari) is coming and what the forecasts for this year will be.
