This subscription right price of 0.93 euros would mean that by buying subscription rights and subscribing, the price per share would be 8.28 euros. (9x0.93+4x6.19)/4=8.28
That is, of course, a possible price if the market considers the company’s value to have dropped there. However, relative to the current EV, 0.93e is too low a price for the subscription right.
