A company such as you state, if it is for sale, will have already hired somebody to analyze and value their company so that THEY know what the proper price to accept would be. It won't matter so much who is shopping.
On the flip side, if PTSC comes-a-shopping, and has a $20M in the bank and an unclear revenue stream, and consequently a share price at 42 cents with 110M shares in its treasury it's negotiating power is LESS than a PTSC that comes-a-shopping with $20M in the bank, a more clarified revenue stream and CONSEQUENTLY a share price of $1, then because of that extra share price value, it's 110M shares in treasury are now worth over TWICE as much as the company that kept everyone in the dark about their financial strength. So instead of paying $10M in cash and offering another $30M in PTSC shares (30M shares) to the company they're trying to purchase, they would have to offer $10M in cash and 71M shares of stock to get to the $30M in PTSC shares. Not to mention the fact that diluting the OS by and EXTRA 42M shares would cause the share price to decrease because of the extra dilution.
So while you're focusing on a potential target thinking that they can drive their price up because PTSC has more money, the truth is, PTSC's display of financial strength and its abililty to provide visibility to the market will provide support to the share price which could double PTSC's purchasing power for the same amount of shares.
