From the article:
Quote: The company’s initial offer for Pentax in 2006 was about 10 percent higher than its market value at the time.
So obviously, even now that Pentax has become profitable, it will take a long time to recuperate from that. In particular, if you only have 1% of shares like the grandson, you'd want the company to be even more profitable.
Sad to see someone talking purely from a money generating perspective, apparantly ignoring the fact that a great brand has been saved from becoming extinct and continues to offer great products in a very competitive field.
