The price of a stock is a combination of the the current value of the company + the present value of the all future revenue.
If a settlement occur and there is an increased in cash, that is an immediate benefit in the price of the stock, in theory it should be a 1 to 1 ratio. The settlement also increases the future revenue for the firm. This increase in future revenue is what would form the premium paid for the stock
Lets say that today stock price is P0
P0= $5
After settlement cash increase therefore stock price after settlement is P1
P1 = P0 + $5(increase in stock price due to cash)
P1 = $10
The present value of future revenue represents the multiple or premium you would pay to own this stock in light of more chance of successful defense of patents let this value be P2
P2 = P1 + $5
P2 = $15
This would be theoretical market price when all of the settlement and future revenue is taken into account. I just used simple numbers to illustrate.
Dividends are revenue that flows to shareholders. If it flows out of the corp it cannot be used for future development. It might be more beneficial to keep in in the company to develop future patents.
If a dividend policy is established, the share price must adjust because there will less money available to the company.
Hope this basic discussion help.s
