If all the shareholders of the company choose to exercise their stock option, the company's outstanding shares would increase by 100 million. The market capitalization of the stock would increase to $60 billion (previous market capitalization + cash received from owners of rights converting their rights to shares), implying a share price of $300 ($60 billion / 200 million shares). If the company were to do nothing with the raised money, its earnings per share (EPS) would be reduced by half. However, if the equity raised by the company is reinvested (e.g. to acquire another company), the EPS may be impacted depending upon the outcome of the reinvestment.
