No, that's not at all correct. Most acquirers want to own 20% of a business before engaging in a takeover bid/negotiation. The poison pill dissuades that. Purchasers lose interest when they see a poison pill because they view management as "hostile". Ever heard of a hostile takeover? Well now you know where that term comes from.
I don't need to check my sources. I'm a professional accountant. Unlike like you (as you previously mentioned), I am a professional.
I remind you of the board rules in regards to being hostile towards posters, especially those that are moderators such as I am.
